Allen-Bradley 20F14NF119JN0NNNNN — Detailed Technical Specifications, Product Introduction, Applications, Advantages and Related Models

The 20F14NF119JN0NNNNN is a high-power industrial AC drive from the PowerFlex 753 series. It is designed for large three-phase motor applications where high current capacity, stable speed control, industrial automation integration and dependable operation are important.

This model is rated for 690 VAC, three-phase input, with a 119 A Normal Duty output rating, 110 kW Normal Duty power, and 98 A Heavy Duty output rating with 90 kW Heavy Duty power.

The drive uses a Frame 6 construction and forced-air cooling. It is configured for DC input with precharge, filtered operation, a common-mode capacitor jumper installed, embedded I/O, standard protection and a blank/no-HIM configuration.

A particularly important characteristic of the 20F14NF119JN0NNNNN is that it has no internal dynamic-braking transistor. This differentiates it from the closely related 20F14NF119JA0NNNNN, which has the same general current and power class but includes a dynamic-braking transistor.

The model is therefore a strong choice for large industrial pumps, fans, blowers, conveyors, process machinery, rollers, mixers, material-handling equipment and other high-power motor-driven systems where the application does not require an integrated internal dynamic-braking transistor.

For cabinet design, the mechanical dimensions should be checked against the actual revision and mechanical drawing of the supplied unit before finalizing mounting holes and service clearances.

2. Brand and Product Series

Brand: Allen-Bradley.

Product Family: PowerFlex 750-Series.

Product Series: PowerFlex 753.

The PowerFlex 753 series is an industrial architecture-class drive family intended for applications requiring considerably more flexibility and integration capability than a basic compact VFD.

The series is suitable for a broad range of industrial motor applications and is available across several voltage and current classes.

The 20F14NF119JN0NNNNN represents a high-power 690 VAC configuration within the PowerFlex 753 range.

3. Product Introduction

The main purpose of the 20F14NF119JN0NNNNN is to provide controlled electrical power to a three-phase AC motor.

Instead of operating a motor continuously at one fixed speed, the drive can regulate motor speed according to the requirements of the machine.

This is particularly useful in industrial equipment because the mechanical load is rarely constant.

A conveyor may need a slow acceleration sequence before reaching its normal operating speed.

A pump may need to adjust its speed according to flow requirements.

A fan may need to respond to changing ventilation demand.

A mixer may need higher torque during startup and a lower speed during processing.

A production roller may need accurate speed control and coordination with other equipment.

The drive provides the electrical control interface between the industrial automation system and the motor.

4. Main Electrical Ratings

Electrical Parameter	Normal Duty	Heavy Duty
Model	20F14NF119JN0NNNNN	20F14NF119JN0NNNNN
Continuous Output Current	119 A	98 A
Power Rating	110 kW	90 kW
Voltage	690 VAC	690 VAC
Phase	3 Phase	3 Phase
Frame	Frame 6	Frame 6
Cooling	Forced Air	Forced Air
Input Type	DC Input with Precharge	DC Input with Precharge
Dynamic Braking	None	None

The most important electrical characteristic is the 119 A Normal Duty rating.

This corresponds to a 110 kW Normal Duty power rating.

Under Heavy Duty conditions, the continuous current rating is 98 A, corresponding to a 90 kW Heavy Duty rating.

This difference should always be considered when selecting the drive for a particular motor.

5. Normal Duty Rating

The 110 kW Normal Duty rating makes this model suitable for large industrial motor applications where the motor normally operates without severe and repeated overload conditions.

Typical Normal Duty applications can include:

• Large centrifugal pumps.
• Large industrial fans.
• Blowers.
• Continuous conveyors.
• Circulation equipment.
• Process machinery with relatively stable loading.
• Large material-handling equipment with moderate torque requirements.

The actual motor nameplate current remains more important than simply comparing the motor’s kW rating with the drive’s nominal power rating.

6. Heavy Duty Rating

The Heavy Duty rating is 98 A / 90 kW.

Heavy Duty selection becomes important when the motor encounters greater torque requirements or more severe overload conditions.

Potential Heavy Duty applications include:

• Heavy conveyors.
• Mixers.
• Agitators.
• High-inertia machines.
• Machinery with difficult starting conditions.
• Machines with frequent acceleration.
• Machines with repeated load changes.
• Process equipment with high torque demand.

For a 90 kW Heavy Duty motor, this model can be a suitable candidate when the actual motor current and complete operating profile are within the drive’s limits.

7. 690 VAC Three-Phase System

The drive is designed for a 690 VAC, three-phase system.

This makes it particularly suitable for large industrial motor installations.

Higher motor voltage can be advantageous in high-power systems because the current required for a given amount of power can be lower than with lower-voltage motor systems.

This can influence:

• Motor selection.
• Cable sizing.
• Switchgear.
• Power distribution.
• Cabinet layout.
• System losses.
• Installation design.

The 690 VAC class is therefore one of the key reasons the 20F14NF119JN0NNNNN is targeted toward larger industrial applications.

8. DC Input with Precharge

The model is configured for DC input with precharge.

The associated DC-bus class is approximately 932 VDC.

This configuration can be useful in systems where a DC bus or common-bus architecture is required.

The precharge function is particularly important in high-power systems because the drive’s DC bus contains substantial capacitance.

When the system is energized, the precharge process controls the initial charging behavior of the DC bus.

This is especially relevant in installations containing multiple drives or other DC-bus equipment.

9. No Internal Dynamic-Braking Transistor

One of the most important details of this particular catalog number is the absence of an internal dynamic-braking transistor.

The 20F14NF119JN0NNNNN does not include the internal DB transistor.

This should not be confused with the closely related 20F14NF119JA0NNNNN.

Both models have the same general 119 A / 110 kW Normal Duty and 98 A / 90 kW Heavy Duty capacity, but their braking configurations are different.

Feature	20F14NF119JN0NNNNN	20F14NF119JA0NNNNN
Voltage	690 VAC	690 VAC
ND Current	119 A	119 A
ND Power	110 kW	110 kW
HD Current	98 A	98 A
HD Power	90 kW	90 kW
Frame	6	6
Cooling	Forced Air	Forced Air
Input	DC + Precharge	DC + Precharge
Filtering	Filtered	Filtered
CM Jumper	Installed	Installed
Dynamic-Braking Transistor	None	Internal DB Transistor
HIM	Blank / No HIM	Blank / No HIM

This difference is important when selecting a drive for a machine with substantial regenerative energy.

If the machine requires dynamic braking, the braking architecture must be evaluated separately.

10. Dynamic-Braking Considerations

During deceleration, a motor can return mechanical energy to the drive’s DC bus.

This effect becomes more significant when the machine has:

• High rotational inertia.
• High operating speed.
• Short stopping time.
• Frequent stopping cycles.
• Large rotating components.
• Heavy conveyor loads.

For these applications, an external braking solution may be required depending on the system design.

Because the 20F14NF119JN0NNNNN does not include an internal braking transistor, the engineer should not assume that a braking resistor can simply be connected directly to the drive without the appropriate switching hardware.

When internal braking capability is required, the 20F14NF119JA0NNNNN is a closely related configuration worth considering.

11. Frame 6 Construction

The drive uses a Frame 6 construction.

This is a large industrial frame suitable for high-power applications.

For preliminary mechanical planning, the drive is approximately:

665.5 mm high × 308 mm wide × 346.4 mm deep.

The product-only weight reference is approximately:

14.51 kg.

Mechanical Parameter	Specification
Model	20F14NF119JN0NNNNN
Frame	Frame 6
Height	Approx. 665.5 mm
Width	Approx. 308 mm
Depth	Approx. 346.4 mm
Approx. Dimensions	Approx. 665.5 × 308 × 346.4 mm
Product Weight	Approx. 14.51 kg
Weight (kg)	14.51 kg
Enclosure	IP20/IP00, NEMA/UL Open Type
Cooling	Forced Air
Mounting	Panel / Cabinet
Installation	Industrial Control Cabinet
Service Clearance	Required
Ventilation	Required

The exact cabinet space required will be larger than the physical drive dimensions because sufficient room must be provided for:

• Power connections.
• Motor cables.
• Control wiring.
• Communication cables.
• Grounding.
• Ventilation.
• Service access.
• Maintenance.

12. Open-Type Enclosure

The drive uses an IP20/IP00, NEMA/UL Open Type construction.

This type of construction is generally intended for installation inside a suitable industrial enclosure.

The surrounding cabinet should provide appropriate protection against:

• Dust.
• Moisture.
• Oil contamination.
• Chemical contamination.
• Accidental contact.
• Mechanical impact.
• Excessive temperature.

The cabinet should also be designed so that the drive’s cooling airflow is not restricted.

13. Forced-Air Cooling

The 20F14NF119JN0NNNNN uses forced-air cooling.

Because the drive is rated at 110 kW Normal Duty, heat management is an important part of the installation.

The cabinet should provide a suitable airflow path.

Cooling Parameter	Consideration
Model	20F14NF119JN0NNNNN
Cooling Method	Forced Air
Cabinet Ventilation	Required
Airflow Path	Must remain unobstructed
Cooling Fans	Require maintenance
Cabinet Temperature	Must remain within allowable limits
Heat Sources	Must be considered
Air Filters	Maintain where used
Service Access	Required
Thermal Design	Important for continuous operation

Poor thermal design can reduce drive reliability even when the electrical rating is otherwise appropriate.

For this reason, the cabinet’s thermal design should be considered at the same time as motor and drive selection.

14. Filtering Configuration

The model uses a filtered configuration with the common-mode capacitor jumper installed.

This configuration is relevant to the drive’s electrical behavior and the overall electromagnetic environment.

The installation should consider:

• Grounding.
• Motor-cable routing.
• Cable length.
• Shielding.
• Cabinet layout.
• Separation of power and control cables.
• Motor insulation.
• System grounding.

Correct installation is particularly important in high-power variable-frequency drive systems.

15. Embedded I/O

The PowerFlex 753 platform includes embedded I/O.

This can simplify basic machine integration.

Typical signals may include:

• Start commands.
• Stop commands.
• Enable signals.
• Speed references.
• Fault status.
• Drive status.
• Analog signals.
• Digital signals.

Embedded I/O can reduce the need for some additional interface hardware and simplify the basic connection between the drive and the machine controller.

16. Industrial Communication

The PowerFlex 753 platform can be integrated into industrial automation systems using appropriate communication options.

A typical architecture can be:

PLC → Industrial Network → PowerFlex 753 → Motor

An HMI can be added:

HMI → PLC → Drive

This arrangement allows the operator and control system to monitor:

• Motor speed.
• Drive status.
• Fault conditions.
• Operating commands.
• Process-related information.

The drive can therefore function as an integrated component of the automation system rather than simply operating as an independent motor controller.

17. Product Application — Large Pumps

Large pumps are an important application for the 20F14NF119JN0NNNNN.

Industrial pumping systems often operate at different flow requirements.

A variable-speed drive can adjust motor speed according to process demand.

Typical applications include:

• Industrial water pumps.
• Cooling-water pumps.
• Process pumps.
• Circulation systems.
• Transfer pumps.
• Water-treatment equipment.
• Industrial pumping stations.
• Process-fluid systems.

For centrifugal pumps, speed control can be especially useful because pump performance changes significantly with operating speed.

18. Product Application — Large Fans

Large industrial fans can require substantial motor power.

The drive can adjust fan speed according to ventilation or process requirements.

Typical applications include:

• Factory ventilation.
• Industrial exhaust.
• Furnace ventilation.
• Dust collection.
• Cooling systems.
• Air-handling systems.
• Process ventilation.
• Large industrial air systems.

Instead of operating continuously at maximum speed, the fan can be controlled according to actual process requirements.

19. Product Application — Large Blowers

Large blowers often need controlled airflow and pressure.

The drive can vary the blower speed while the overall control system monitors the process.

Typical applications include:

• Pneumatic conveying.
• Process air.
• Industrial drying.
• Dust collection.
• Furnace air.
• Combustion air.
• Chemical processing.
• Manufacturing equipment.

The actual torque curve should be considered when determining whether Normal Duty or Heavy Duty operation is appropriate.

20. Product Application — Conveyor Systems

The 20F14NF119JN0NNNNN can be used for large conveyor systems.

Conveyors carrying heavy material can have significant starting torque requirements.

Variable-speed operation provides:

• Controlled acceleration.
• Adjustable production speed.
• Controlled deceleration.
• Improved process coordination.
• Reduced mechanical shock.

Potential applications include:

• Mining conveyors.
• Bulk-material conveyors.
• Manufacturing conveyors.
• Transfer conveyors.
• Warehouse material handling.
• Processing conveyors.
• Heavy industrial transportation systems.

For conveyors with substantial inertia, the braking system should be evaluated separately because this model does not include an internal dynamic-braking transistor.

21. Product Application — Rollers

Industrial rollers frequently require accurate speed control.

Potential applications include:

• Steel processing.
• Paper processing.
• Printing.
• Packaging.
• Material processing.
• Production lines.
• Web handling.

Where several rollers operate together, communication and feedback functions can be useful for maintaining coordinated machine operation.

22. Product Application — Mixers and Agitators

Large mixers and agitators can present challenging torque profiles.

The machine may require high torque during startup and lower torque after the material begins moving.

The drive can provide controlled acceleration and adjustable speed.

Typical applications include:

• Chemical mixing.
• Food processing.
• Batch processing.
• Industrial tanks.
• Material preparation.
• Process machinery.
• Manufacturing equipment.

Where breakaway torque is particularly high, the Heavy Duty rating should be considered carefully.

23. Product Application — Process Machinery

The drive is also suitable for large process machinery.

Potential applications include:

• Production machines.
• Processing equipment.
• Packaging equipment.
• Material-processing machinery.
• Large auxiliary machines.
• Manufacturing lines.
• Industrial mechanical systems.

The PowerFlex 753 platform is particularly useful when the machine requires integrated control, communication or feedback functions in addition to basic variable-speed operation.

24. Product Advantages

24.1 High 119 A Output Rating

It allows the drive to control substantially larger motors than compact drive families.

The 110 kW Normal Duty rating places the model in a high-power industrial category.

24.2 110 kW Normal Duty Capacity

A 110 kW Normal Duty rating makes this model suitable for large pumps, fans, blowers and other continuously operated industrial machines.

This provides a useful capacity level between smaller 90 kW configurations and larger drive ratings.

24.3 90 kW Heavy Duty Capacity

The 90 kW Heavy Duty rating provides considerable overload capability for demanding industrial applications.

This can be important for machines where torque requirements are higher during starting or normal operation.

24.4 690 VAC Capability

The 690 VAC rating makes this drive particularly suitable for large industrial motor systems.

It is a major distinguishing characteristic compared with many compact 380–480 VAC drive products.

24.5 DC Input with Precharge

The DC input and precharge configuration can be useful in common-bus applications.

This provides flexibility for systems where several drives or power-conversion components share a DC power architecture.

25. Advantages for Machine Builders

The 20F14NF119JN0NNNNN is useful for machine builders because the PowerFlex 753 platform can be applied across a broad range of motor sizes.

A common drive architecture can be used for multiple machines.

This can simplify:

• Programming.
• Commissioning.
• Maintenance.
• Spare-parts management.
• Technician training.
• Troubleshooting.
• Automation integration.

For large machines, this type of platform standardization can be especially valuable.

26. Advantages for Maintenance

Technicians can become familiar with:

• Parameter structures.
• Fault diagnostics.
• Communication settings.
• I/O.
• Feedback options.
• Motor-control functions.

29. Five Recommended Same-Series or Closely Related Models

The following five models are useful for comparison because they belong to the same PowerFlex 753 family or are immediately related to the target model.

Model	Series	Voltage	ND Current	ND Power	HD Current	HD Power	Dynamic Braking	Frame	Weight (kg)
20F14NF061JN0NNNNN	PowerFlex 753	690 VAC	61 A	55 kW	50 A	45 kW	None	6	Approx. 14.51
20F14NF082JN0NNNNN	PowerFlex 753	690 VAC	82 A	75 kW	61 A	55 kW	None	6	Approx. 14.51
20F14NF098JN0NNNNN	PowerFlex 753	690 VAC	98 A	90 kW	82 A	75 kW	None	6	Approx. 14.51
20F14NF119JN0NNNNN	PowerFlex 753	690 VAC	119 A	110 kW	98 A	90 kW	None	6	14.51
20F14NF119JA0NNNNN	PowerFlex 753	690 VAC	119 A	110 kW	98 A	90 kW	Internal DB Transistor	6	Approx. 14.51

The five models provide a practical progression around the target model.

The 20F14NF061JN0NNNNN is appropriate for a lower-power 690 VAC application.

The 20F14NF082JN0NNNNN provides a 75 kW Normal Duty rating.

The 20F14NF098JN0NNNNN increases the Normal Duty rating to 90 kW.

The target 20F14NF119JN0NNNNN reaches 110 kW Normal Duty.

The 20F14NF119JA0NNNNN provides the same basic 119 A / 110 kW capacity but adds an internal dynamic-braking transistor.

30. Same-Series Electrical Comparison

Model	ND Current	ND Power	HD Current	HD Power	Dynamic Braking
20F14NF061JN0NNNNN	61 A	55 kW	50 A	45 kW	None
20F14NF082JN0NNNNN	82 A	75 kW	61 A	55 kW	None
20F14NF098JN0NNNNN	98 A	90 kW	82 A	75 kW	None
20F14NF119JN0NNNNN	119 A	110 kW	98 A	90 kW	None
20F14NF119JA0NNNNN	119 A	110 kW	98 A	90 kW	Internal DB Transistor

This comparison shows that the target model occupies a high position within the 690 VAC PowerFlex 753 range.

The jump from the 98 A model to the 119 A model increases Normal Duty power from 90 kW to 110 kW.

The Heavy Duty rating increases from 75 kW to 90 kW.

The JA version does not increase the basic current or power rating; its principal difference is the integrated braking-transistor configuration.

31. Five Same-Brand Popular or Related Models

The following models represent other well-known products within the same brand portfolio.

Model	Series	Voltage Class	Current Class	Typical Power Class	Cooling	Product Position	Approx. Dimensions	Weight (kg)
25B-D017N104	PowerFlex 525	480 VAC Class	17 A	Approx. 7.5 kW	Air Cooled	Compact drive	Approx. 200 × 300 × 180 mm	Approx. 5
25B-D024N104	PowerFlex 525	480 VAC Class	24 A	Approx. 11 kW	Air Cooled	Compact drive	Approx. 230 × 350 × 190 mm	Approx. 6–8
25B-D043N114	PowerFlex 525	480 VAC Class	43 A	Approx. 22 kW	Air Cooled	Compact / medium machine	Approx. 250 × 400 × 220 mm	Approx. 10–15
20F11NC043JA0NNNNN	PowerFlex 753	480 VAC Class	43 A	Approx. 22 kW	Air Cooled	Industrial architecture drive	Approx. 250–300 × 500–700 × 300 mm	Approx. 30–45
20G11NC043JA0NNNNN	PowerFlex 755	480 VAC Class	43 A	Approx. 22 kW	Air Cooled	Advanced industrial drive	Approx. 250–300 × 500–700 × 300 mm	Approx. 30–45

These five products are useful for portfolio comparison rather than direct replacement.

The PowerFlex 525 products are generally more compact and are intended for smaller and medium-sized machines.

The PowerFlex 753 family is more appropriate for larger industrial equipment.

The PowerFlex 755 family is generally considered for applications where more advanced control capabilities are needed.

Most importantly, the voltage class must be checked before selecting any alternative.

A 480 VAC model cannot simply replace a 690 VAC model without verifying the motor, power system and complete application requirements.

32. Comparison with the 20F14NF098JN0NNNNN

Parameter	20F14NF098JN0NNNNN	20F14NF119JN0NNNNN
Voltage	690 VAC	690 VAC
ND Current	98 A	119 A
ND Power	90 kW	110 kW
HD Current	82 A	98 A
HD Power	75 kW	90 kW
Frame	6	6
Cooling	Forced Air	Forced Air

Filtering	Filtered	Filtered
CM Jumper	Installed	Installed
Dynamic Braking	None	None
Approx. Dimensions	Frame 6 class	Frame 6 class
Weight (kg)	Approx. 14.51	14.51

The 20F14NF119JN0NNNNN provides a significant increase in capacity over the 98 A model.

The Normal Duty rating rises from 90 kW to 110 kW.

The Heavy Duty rating rises from 75 kW to 90 kW.

If a motor is approaching the current limit of the 98 A configuration, the 119 A model provides a useful additional margin, subject to the actual motor nameplate current and application duty.

33. Comparison with the 20F14NF119JA0NNNNN

Parameter	20F14NF119JN0NNNNN	20F14NF119JA0NNNNN
Voltage	690 VAC	690 VAC
ND Current	119 A	119 A
ND Power	110 kW	110 kW
HD Current	98 A	98 A
HD Power	90 kW	90 kW
Frame	6	6
Cooling	Forced Air	Forced Air
Input	DC + Precharge	DC + Precharge
Filtering	Filtered	Filtered
CM Jumper	Installed	Installed
Dynamic Braking	None	Internal DB Transistor
HIM	Blank / No HIM	Blank / No HIM
Approx. Dimensions	Frame 6 class	Frame 6 class
Weight (kg)	14.51	Approx. 14.51

This is the most important comparison for this catalog number.

The two drives are very similar in terms of voltage, current, power, frame size and general architecture.

The principal difference is the dynamic-braking configuration.

The JN version does not include an internal dynamic-braking transistor.

The JA version includes one.

Therefore, if the application does not require integrated dynamic braking, the JN configuration may be a suitable choice.

If controlled braking is a major requirement, the JA configuration may be more appropriate.

34. Motor Selection Considerations

Motor selection should be based on the actual motor nameplate rather than simply selecting the same kW value.

Important parameters include:

Motor Parameter	Selection Requirement
Motor Voltage	Must match the 690 VAC system
Motor Current	Must be within the applicable drive rating
Motor Power	Compare with 110 kW ND / 90 kW HD
Motor Frequency	Verify system requirements
Motor Speed	Check required speed range
Starting Torque	Evaluate carefully
Continuous Torque	Evaluate thermal loading
Peak Torque	Evaluate overload requirements
Motor Type	Confirm compatibility
Feedback	Determine whether feedback is necessary
Braking	Evaluate regenerative energy
Motor Cable	Consider length and installation
Environment	Check temperature, dust, moisture and vibration

For a 110 kW Normal Duty motor, this drive is a logical candidate.

For a 90 kW Heavy Duty motor, it can also be appropriate when the actual motor current and operating profile are within the drive’s limits.

For motors above these ratings, a larger drive should be evaluated.

35. Application Selection Guide

Application	Suitability	Main Consideration
Large centrifugal pump	Excellent	Normal Duty operation
Large industrial fan	Excellent	Speed regulation
Large blower	Excellent	Process airflow
Heavy conveyor	Very Good	Starting torque and braking

36. Typical Industrial Control Architecture

A typical installation can be structured as:

PLC / Controller → Industrial Network → PowerFlex 753 Drive → Three-Phase Motor → Mechanical Load

A more complete system may be:

HMI → PLC → Industrial Network → Drive → Motor → Machine

Additional feedback can be included:

Encoder → Feedback Interface → Drive

Because the target model does not include an internal dynamic-braking transistor, a system requiring braking may require an appropriate external braking architecture.

38. Installation Considerations

The first consideration is cabinet size.

The Frame 6 drive requires adequate physical space around the unit.

The preliminary dimensions are approximately 665.5 × 308 × 346.4 mm.

The second consideration is weight.

A product weight of approximately 14.51 kg should be allowed for the drive itself, while the total installed assembly may weigh considerably more after cables, cabinet hardware and accessories are added.

The third consideration is airflow.

The drive uses forced-air cooling, so the cabinet must provide adequate ventilation.

The fourth consideration is electrical cable routing.

Motor cables, incoming power cables and control cables should be arranged appropriately.

The fifth consideration is grounding.

A properly designed grounding system is essential for industrial drive operation.

The sixth consideration is braking.

Since this model has no internal dynamic-braking transistor, braking requirements should be evaluated before the final drive configuration is approved.

39. Maintenance Considerations

Preventive maintenance should include inspection of:

• Cooling fans.
• Airflow paths.
• Cabinet filters.
• Power connections.
• Grounding connections.
• Control wiring.
• Communication wiring.
• Motor cables.
• Drive fault history.
• Cabinet temperature.

Dust accumulation can reduce cooling performance.

Loose power connections can produce additional heat.

Poor cable routing can increase electrical interference.

The cooling system should therefore be included in the plant’s regular maintenance program.

The PowerFlex 753 is a strong choice for large industrial machinery.

The PowerFlex 755 family can become more attractive when the application has particularly demanding control or system-integration requirements.

45. Catalog Number Configuration

The catalog number 20F14NF119JN0NNNNN contains several important configuration characteristics.

The product belongs to the PowerFlex 753 family.

The configuration is for the 690 VAC class.

The 119 current designation corresponds to the 119 A class.

The model uses DC input with precharge.

The filtering configuration is filtered with the common-mode capacitor jumper installed.

The relevant braking configuration specifies no internal dynamic-braking transistor.

The product also has a blank/no-HIM configuration.

These configuration details are important because two PowerFlex 753 drives can have similar current and power ratings but differ significantly in their options.

46. Why the JN Configuration Can Be a Good Choice

The absence of an internal dynamic-braking transistor is not necessarily a disadvantage.

Many industrial applications do not require aggressive braking.

For example, a large centrifugal pump may have a relatively gradual stopping requirement.

A large fan may also be allowed to coast down rather than stop rapidly.

In such applications, paying for or specifying an integrated braking transistor may not be necessary.

The JN configuration can therefore be a practical choice when the application does not require internal dynamic braking.

47. When the JA Configuration May Be Better

The closely related JA configuration becomes more attractive when the machine requires controlled braking.

Potential examples include:

• High-inertia rollers.
• Large conveyors.
• Rapid-cycle machinery.
• Large rotating equipment.
• Applications with frequent stopping.
• Equipment requiring short deceleration times.

The important point is that the difference between JN and JA is primarily functional rather than simply a difference in motor power.

48. Selection Guide Between Related 690 VAC Models

Motor / Application Requirement	Recommended Model Direction
Around 55 kW ND	20F14NF061JN0NNNNN
Around 75 kW ND	20F14NF082JN0NNNNN
Around 90 kW ND	20F14NF098JN0NNNNN
Around 110 kW ND, no internal DB transistor	20F14NF119JN0NNNNN
Around 110 kW ND, internal DB transistor required	20F14NF119JA0NNNNN
Around 90 kW HD	20F14NF119JN0NNNNN or 20F14NF119JA0NNNNN, depending on braking needs
Higher-power HD application	Consider a larger frame/current class

This selection approach makes the target model particularly useful for large motors where 90 kW is not enough but the next higher capacity is not yet required.

49. Overall Product Evaluation

The 20F14NF119JN0NNNNN is a high-power industrial AC drive designed for large three-phase motor applications.

Its principal rating is 119 A Normal Duty / 110 kW, with a 98 A / 90 kW Heavy Duty rating.

The 690 VAC class makes it particularly appropriate for large industrial motor systems.

The Frame 6 architecture provides a substantial platform for high-power machinery.

The drive uses forced-air cooling and should be installed in an appropriately designed industrial enclosure.

The approximate planning dimensions are 665.5 × 308 × 346.4 mm, while the product-weight reference is approximately 14.51 kg.

The exact cabinet design should include additional room for wiring, ventilation, grounding, service access and associated equipment.

One of the defining characteristics of this exact catalog number is the absence of an internal dynamic-braking transistor.

This is an important difference from the closely related 20F14NF119JA0NNNNN.

The JN configuration is therefore particularly suitable for applications where internal dynamic braking is not required.

For applications involving substantial regenerative energy, high inertia or rapid stopping, the braking system should be evaluated separately.

The drive’s DC input with precharge configuration can also be valuable in common-bus and DC-bus applications.

The filtered configuration and installed common-mode capacitor jumper provide a defined electrical configuration that should be considered when designing the complete installation.

The embedded I/O makes basic machine integration straightforward.

Communication and feedback options allow the drive to participate in larger industrial automation architectures.

This makes the product suitable for systems in which the drive must communicate with a PLC, HMI, feedback device or other industrial equipment.

The 20F14NF119JN0NNNNN is especially well suited to large pumps, industrial fans, blowers, conveyors, rollers, mixers, process machinery and material-handling systems.

For a 110 kW Normal Duty motor, it is a natural candidate when the actual motor current and operating conditions fit within the drive’s ratings.

For a 90 kW Heavy Duty motor, the model also provides a useful capacity level.

For applications requiring an integrated dynamic-braking transistor, the closely related JA configuration should be evaluated instead.

In practical terms, the 20F14NF119JN0NNNNN can be summarized as a 690 VAC, three-phase, 119 A, 110 kW Normal Duty / 90 kW Heavy Duty, Frame 6, forced-air-cooled PowerFlex 753 industrial AC drive with DC input and precharge, filtered configuration, common-mode capacitor jumper installed, embedded I/O, standard protection, blank/no-HIM configuration and no internal dynamic-braking transistor.

Its combination of high power capacity, 690 VAC operation, modular architecture, embedded I/O and industrial control capability makes it a strong choice for large motor-driven equipment where reliable variable-speed control and automation integration are required.
