20DJ248A0NNNACGNE — Detailed Product Overview and Technical Guide

1. Product Overview

The 20DJ248A0NNNACGNE is a high-power industrial AC drive in the PowerFlex 700S, 20D series.

It belongs to the 650 VDC input class and has a 248 A continuous output-current rating. In the standard rating table, this corresponds to approximately 200 HP normal-duty and 150 HP heavy-duty operation. The drive is identified as a Frame 6 unit.

This is not a small general-purpose VFD. It is designed for larger industrial motors and applications where the drive needs to provide substantial current capacity, controlled acceleration and deceleration, advanced motor-control functions and integration into an industrial automation system.

The 20DJ248A0NNNACGNE is particularly suitable for large conveyors, pumps, fans, blowers, compressors, material-handling equipment and other process machinery where a high-power variable-speed motor-control system is required.

The 20D family also supports a wide range of current ratings. The 248 A model sits above the 156 A and 180 A versions and below the larger 261 A, 300 A and 385 A configurations. This makes it a useful choice when the motor requires substantially more current than a 100–150 HP-class drive but does not require one of the very largest units.

3. Brand and Product Series

Category	Information
Brand	Allen-Bradley
Product family	PowerFlex
Product series	PowerFlex 700S
Catalog family	20D
Model	20DJ248A0NNNACGNE
Drive category	High-performance AC drive
Input type	650 VDC
Application class	Industrial high-power motor control
Control platform	PowerFlex 700S
Mechanical frame	Frame 6

The PowerFlex 700S series was developed for applications that need more advanced control than a basic adjustable-frequency drive.

The series is particularly appropriate when motor speed, torque, acceleration, process control and automation-system integration are important.

The 20D family includes both AC-input and DC-input configurations. The J voltage designation identifies the 650 VDC class used by the 20DJ family. The catalog tables show the 20DJ248 alongside 20DJ096, 20DJ125, 20DJ156 and 20DJ180 in the 650 VDC product group.

---

4. Model Number

The complete catalog number is:

20DJ248A0NNNACGNE

For maintenance and replacement work, the complete catalog number should always be retained.

The first part, 20D, identifies the PowerFlex 700S/20D family.

The J identifies the 650 VDC input class.

The 248 identifies the 248 A current class.

The remaining configuration characters specify the particular drive arrangement and option combination.

This is important because drives with the same 248 A electrical rating can have different configuration codes, precharge arrangements, enclosure arrangements, control options, feedback options and other hardware.

A replacement should therefore be selected using the complete catalog number and the actual installed hardware, rather than matching only the 248 A rating.

---

---

6. Normal-Duty and Heavy-Duty Ratings

One of the most important points when selecting this drive is the difference between normal-duty and heavy-duty operation.

The 20DJ248 is rated at approximately 200 HP for normal duty and 150 HP for heavy duty.

Duty Classification	Motor Rating	Approx. Metric Power
Normal Duty	200 HP	132 kW
Heavy Duty	150 HP	110 kW

The difference exists because heavy-duty applications generally place greater thermal and overload demands on the drive.

For example, a large fan may have relatively predictable torque requirements, while a conveyor or processing machine may require considerably more torque during acceleration or under overload conditions.

Therefore, selecting a drive according to horsepower alone is not recommended.

Motor full-load current and actual machine duty should always be considered.

---

7. Output Current Capability

The 248 A continuous output rating is the central characteristic of this model.

The drive can provide:

• 248 A continuous output.
• 273 A for one minute.
• 372 A for three seconds.

This gives the drive additional short-term current capability for acceleration and transient load conditions.

For a large industrial motor, this extra current capability can be important.

During acceleration, the motor may require significantly more current than it consumes at steady-state speed.

The drive’s overload capability allows the motor to accelerate without immediately exceeding the drive’s short-term current limits.

The actual overload capability available in a particular application depends on temperature, programmed operating conditions and other drive parameters.

---

8. 650 VDC Input

The 20DJ248A0NNNACGNE is a DC-input drive rather than a conventional three-phase AC-input drive.

Its voltage class is 650 VDC.

This architecture is useful in industrial systems that use a common DC bus.

A common DC-bus system can be advantageous when multiple drives are operating together because the DC bus provides a shared electrical energy path.

For example, one motor may be accelerating while another motor is decelerating.

Depending on the complete system architecture, energy from one drive can potentially be shared through the common DC bus rather than being handled entirely by independent AC input sections.

This can be useful in coordinated machinery and multi-drive installations.

---

9. DC Common-Bus Applications

Common-bus systems are frequently considered for applications with multiple drives.

Typical examples include:

• Large production lines.
• Multi-motor conveyors.
• Material-processing equipment.
• Paper and converting machinery.
• Large machine systems.
• Coordinated process equipment.
• Industrial winding systems.
• Multi-axis industrial machinery.

The system designer must provide appropriate DC-bus protection.

The technical documentation specifies protective-device arrangements for 650 VDC common-bus drives, including fusing requirements and appropriate disconnect equipment.

This is an engineering issue that should not be treated as an optional accessory.

---

10. High-Performance Drive Architecture

The PowerFlex 700S platform is intended for applications that require more than basic speed control.

A simple VFD may primarily control output frequency and voltage.

A high-performance drive can also manage motor torque, speed response, acceleration, deceleration and other control functions.

This makes the 20DJ248A0NNNACGNE more suitable for engineered industrial machinery.

The drive is particularly useful where the relationship between motor speed and machine performance is important.

Examples include:

• High-speed production machinery.
• Large conveyors.
• Process equipment.
• Material-handling systems.
• Large pumps.
• Large fans.
• High-inertia rotating equipment.

---

11. Main Product Advantages

11.1 High Output Current

The 248 A continuous current rating provides substantial capacity for large motors.

This is the primary reason to select this model instead of a smaller 20D drive.

The drive provides a significant increase over the 96 A, 125 A, 156 A and 180 A configurations in the same 650 VDC family.

---

11.2 High Short-Term Overload Capacity

The 273 A one-minute and 372 A three-second ratings provide additional short-duration capacity.

This can be useful during acceleration and temporary load changes.

The capability is particularly relevant for machines where the motor must produce additional torque for a short period.

---

11.3 Large Motor Compatibility

The 200 HP normal-duty rating makes this drive appropriate for substantial industrial motors.

The 150 HP heavy-duty rating makes it suitable for applications where more demanding torque and overload characteristics must be considered.

---

11.4 Common DC-Bus Capability

The DC-input architecture makes this model suitable for common-bus systems.

This can simplify the power architecture of multi-drive systems and can provide opportunities for energy sharing between drives.

---

11.5 Advanced Motor Control

The PowerFlex 700S platform is designed for applications that require more precise control than a basic VFD.

This can be valuable when:

• Speed regulation is important.
• Torque response is important.
• Acceleration must be controlled precisely.
• Multiple motors must work together.
• The drive is part of a larger automated process.

---

11.6 Industrial Application Flexibility

The drive can be applied to a wide range of industrial machinery.

It is not limited to one particular type of motor load.

The same general drive platform can be used for pumps, fans, conveyors and process machinery, provided the electrical and mechanical requirements remain within the drive’s limits.

---

12. Product Applications

12.1 Large Conveyor Systems

Large conveyors are one of the strongest applications for this type of drive.

A large conveyor can contain substantial mechanical inertia.

If the motor starts too quickly, high torque can be transferred to:

• Gearboxes.
• Couplings.
• Shafts.
• Belts.
• Chains.
• Bearings.
• Conveyor structures.

A variable frequency drive allows acceleration to be controlled.

This makes starting smoother and can reduce mechanical shock.

---

13. Mining and Bulk Material Handling

The 248 A capacity makes the drive suitable for many medium-to-large material-handling systems.

Possible applications include:

• Ore conveyors.
• Bulk material conveyors.
• Transfer systems.
• Feed conveyors.
• Processing equipment.
• Crushing-related auxiliary machinery.
• Industrial material handling.

Heavy-duty rating should be considered carefully because material-handling loads can have significant torque requirements.

---

14. Large Pump Systems

Large pumps are another suitable application.

A pump may not need to operate continuously at maximum speed.

Variable-speed control can allow the pump to respond to changes in:

• Pressure.
• Flow.
• Tank level.
• Process demand.
• Cooling requirements.
• Water consumption.

This can provide better process control than a fixed-speed motor.

---

15. Large Fan and Blower Systems

Large fans and blowers can also use variable-speed control.

Airflow requirements often change throughout the day or according to production conditions.

The motor can operate at lower speed when full airflow is not required.

This can provide both process flexibility and potential energy savings.

Typical applications include:

• Industrial ventilation.
• Exhaust systems.
• Cooling towers.
• Process-air systems.
• Dust extraction.
• Combustion-air systems.

---

16. Compressor Applications

The drive can also be considered for large compressors where the compressor manufacturer permits variable-speed operation.

Compressor applications require careful analysis.

The designer should evaluate:

• Minimum speed.
• Maximum speed.
• Starting torque.
• Lubrication requirements.
• Cooling.
• Pressure control.
• Operating envelope.
• Acceleration time.

A drive that is correctly sized electrically can still be unsuitable if the compressor’s mechanical operating range is incompatible with the proposed speed range.

---

17. Process Machinery

The 20DJ248A0NNNACGNE can be useful in process machinery where motor speed is directly related to production conditions.

Potential applications include:

• Mixers.
• Agitators.
• Material-processing machines.
• Large production lines.
• Winding equipment.
• Rotating process equipment.
• Large industrial machinery.

---

18. High-Inertia Machinery

High-inertia loads are particularly important when selecting a large VFD.

Examples include:

• Large fans.
• Large flywheel systems.
• Centrifuges.
• Rollers.
• Large conveyors.
• Heavy rotating machinery.

During deceleration, stored mechanical energy can return to the DC bus.

This means braking must be evaluated as carefully as acceleration.

If the machine needs frequent rapid stopping, an appropriate braking or regenerative solution may be necessary.

---

19. Dimensions and Weight

The 20DJ248 is a Frame 6 drive. The technical data identifies Frame 6 for the 248 A configuration.

The exact physical dimensions can depend on the specific enclosure and mechanical arrangement.

For a high-power drive, it is important to distinguish the drive itself from a complete electrical cabinet.

The cabinet may contain:

• DC disconnects.
• Fuses.
• Busbars.
• Cooling equipment.
• Control equipment.
• Communication components.
• Terminal assemblies.
• Protective devices.

Consequently, the final installed cabinet will be larger and heavier than the drive assembly alone.

20DJ261	PowerFlex 700S / 20D	261 A	287 A	410 A	200 HP	150 HP	9	Frame 9; verify drawing	Configuration-dependent

The 650 VDC rating tables show the current and horsepower progression for the 20DJ125, 20DJ156, 20DJ180, 20DJ248 and 20DJ261 configurations.

---

22. Same-Series Comparison

Model	Current	Normal-Duty HP	Heavy-Duty HP	Frame	Relative Capacity
20DJ125	125 A	100	75	5	Lower
20DJ156	156 A	125	100	6	Lower
20DJ180	180 A	150	125	6	Lower
20DJ248	248 A	200	150	6	Reference
20DJ261	261 A	200	150	9	Slightly higher current
20DJ300	300 A	250	200	9	Higher
20DJ385	385 A	300	250	10	Much higher

The 20DJ248 is therefore positioned as a high-capacity Frame 6 drive, immediately below the larger 261 A and 300 A configurations in the same general 650 VDC family.

---

23. Five Related Models from the Same Product Family

Model	Output Current	Normal Duty	Heavy Duty	Frame	Approx. Power	Application
20DJ125	125 A	100 HP	75 HP	5	75 kW class	Medium-large industrial motor
20DJ156	156 A	125 HP	100 HP	6	90 kW class	Large pump / conveyor

The 20DJ300 and 20DJ385 provide substantial additional capacity when the 248 A drive is insufficient.

---

24. Five Related Models from the Same Brand

For a broader product selection, the following models are useful comparison points across the wider PowerFlex range.

Model	Product Family	Current / Power Class	Typical Application	Control Level	Dimensions	Weight (kg)
20DD248A0ENNANANE	PowerFlex 700S / 20D	248 A / 200 HP ND	Large industrial machinery	High performance	Frame 6; verify drawing	Configuration-dependent

20G11RD011AA0NNNNN	PowerFlex 755	11 A class	Advanced machine and process control	Advanced	Frame-dependent	Configuration-dependent

The first three entries are closer technical relatives of the 20DJ248, while the 753 and 755 families are broader alternatives for systems where the required power level or control architecture is different.

---

25. Five Commonly Encountered Models from the Same Brand

Model	Family	Typical Power Level	Main Application	Suitable for 20DJ248 Replacement?	Dimensions	Weight (kg)
20F11FD065AA0NNNNN	PowerFlex 753	Approx. 50 HP class	Pumps, fans, conveyors	No direct replacement	Configuration-dependent	Configuration-dependent

20BB104A0AYNANC0	PowerFlex 700	104 A class	Medium-large motor	Too small for a 248 A application	Configuration-dependent	Configuration-dependent

These are better treated as product-family comparison points rather than direct one-for-one substitutions.

A modern replacement should be evaluated against voltage, current, duty rating, control requirements, communications, braking, feedback and cabinet dimensions.

---

26. Application Suitability

Application	Suitability	Main Reason
Large conveyor	Excellent	High current and controlled acceleration
Mining conveyor	Excellent	Large motor capacity
Bulk material handling	Excellent	High-power variable speed
Large centrifugal pump	Excellent	Variable-speed process control
Large fan	Excellent	Adjustable speed
Industrial blower	Excellent	High-power motor control
Compressor	Good	Requires compressor-specific review
Mixer	Good	High torque capability
Process machinery	Excellent	Advanced drive architecture
High-inertia machine	Good	Braking must be evaluated
Hoist	Requires engineering	Braking and load control are critical
Small motor	Poor choice	Drive is oversized
Servo positioning	Not primary application	Dedicated servo architecture is generally preferable

---

27. Conveyor Application Advantages

For a large conveyor, the 20DJ248 provides several practical benefits.

The first is controlled acceleration.

A large conveyor system can have considerable mechanical inertia.

If the motor receives full power immediately, the system may experience a sudden torque increase.

A properly configured drive can gradually increase motor speed.

This can reduce mechanical shock and improve the life of belts, gearboxes, shafts and couplings.

The drive can also allow conveyor speed to be adjusted according to production requirements.

---

28. Pump Application Advantages

For pump systems, the drive can regulate motor speed according to process requirements.

For example, if a water system needs less flow, the motor can run at a lower speed.

This can be more efficient than continuously operating at full speed and reducing flow mechanically.

The actual energy-saving potential depends on the pump curve, system resistance and operating profile.

The drive should therefore be evaluated together with the hydraulic system rather than as an isolated component.

---

29. Fan and Blower Application Advantages

Large fans often operate under changing airflow requirements.

A variable-speed drive can adjust fan speed according to the process.

Potential benefits include:

• Better airflow control.
• Reduced mechanical shock.
• Improved process stability.
• Potential energy savings.
• Reduced need for mechanical throttling.

For large industrial ventilation systems, these benefits can be significant.

---

30. Heavy Industrial Applications

The 248 A capacity makes the drive particularly useful for industrial machinery with large motors.

Examples include:

• Steel-processing equipment.
• Cement plants.
• Mining systems.
• Bulk material handling.
• Large manufacturing lines.
• Water-treatment plants.
• Industrial utility systems.
• Large process plants.

In these environments, drive selection should include a review of ambient temperature, dust, vibration, motor cable length and cabinet cooling.

---

31. Mechanical Installation

A Frame 6 high-power drive requires adequate cabinet space.

The cabinet must provide enough room for:

• Power connections.
• DC-bus connections.
• Motor connections.
• Control wiring.
• Communication wiring.
• Cooling airflow.
• Service access.
• Protective devices.

The cabinet thermal calculation is especially important.

A drive with a published heat-loss value still requires a complete cabinet thermal analysis because other electrical components also generate heat.

---

32. Cooling Requirements

The technical data lists approximately 2115 W of drive power loss for the 20DJ248 rating.

This is significant.

More than two kilowatts of heat can require substantial cabinet cooling.

The actual cooling solution depends on:

• Cabinet size.
• Ambient temperature.
• Other heat-generating equipment.
• Altitude.
• Ventilation.
• Enclosure type.
• Duty cycle.
• Installation environment.

A poorly designed cabinet can cause unnecessary thermal stress and reduce drive reliability.

---

33. Environmental Considerations

The 20DJ248 is intended for industrial installation.

The complete system should protect the drive from:

• Excessive dust.
• Water.
• Condensation.
• Corrosive chemicals.
• Conductive contamination.
• Excessive ambient temperature.
• Excessive vibration.
• Inadequate ventilation.

The exact environmental rating depends on the physical configuration.

Therefore, the drive should not be assumed to be suitable for direct outdoor installation without an appropriate enclosure.

---

34. Braking and Deceleration

Braking is especially important for a 248 A drive.

A large motor connected to a high-inertia machine can return substantial energy to the DC bus during deceleration.

This can cause DC-bus voltage to rise.

The application may therefore require:

• Longer deceleration ramps.
• External braking hardware.
• Regenerative equipment.
• Mechanical braking.
• A different drive configuration.

The correct solution depends on the actual machine.

A conveyor with a moderate stopping time has very different braking requirements from a large high-speed centrifuge.

---

35. Motor Selection

The motor should be selected according to actual current and duty rather than horsepower alone.

For a 200 HP motor application, check:

Motor Parameter	Why It Matters
Rated voltage	Must match system
Full-load current	Determines drive sizing
Rated frequency	Required for control
Rated speed	Determines operating range
Power factor	Important for electrical loading
Efficiency	Affects system power
Service factor	Affects motor loading
Starting torque	Important for acceleration
Breakdown torque	Important for heavy loads
Insulation	Important for inverter operation
Cooling method	Important at low speed
Encoder	Required for some control strategies

---

36. Installation Parameter Checklist

Item	Requirement
DC-bus voltage	Verify
DC-bus protection	Required
Fuse rating	Verify against application
Disconnect	Required
Motor current	Verify
Motor voltage	Verify
Motor cable	Correctly sized
Grounding	Required
Cabinet cooling	Required
Ambient temperature	Verify
Altitude	Verify
Motor cable length	Verify
EMC	Evaluate
Braking	Evaluate
Feedback	Verify
Communications	Verify
Parameter backup	Recommended
Spare parts	Recommended

The published protection information for the 20DJ248 identifies a 272 A DC input rating and a 400 A non-time-delay fuse class for the applicable 650 VDC configuration.

---

37. Maintenance Considerations

For an industrial drive of this size, preventive maintenance is important.

Recommended maintenance activities include:

• Checking cooling fans.
• Inspecting ventilation paths.
• Checking power connections.
• Inspecting DC-bus connections.
• Checking motor cables.
• Reviewing drive fault history.
• Checking control wiring.
• Inspecting communication connections.
• Checking signs of overheating.
• Cleaning contamination where appropriate.
• Maintaining a backup of drive parameters.
• Recording the complete catalog number.
• Recording installed option hardware.

The final two points are particularly important for older industrial installations.

A complete parameter backup can save significant commissioning time if the drive must be replaced.

---

38. Replacement Considerations

If this drive is being used as an existing machine component, a replacement should not be selected simply because another drive has approximately 200 HP capacity.

The following items must be compared:

Replacement Parameter	Importance
Full catalog number	Critical
650 VDC input class	Critical
Continuous output current	Critical
Normal-duty rating	Critical
Heavy-duty rating	Critical
Frame size	Important
Control architecture	Critical
Feedback	Critical if used
Communication	Critical
Braking	Critical
DC-bus arrangement	Critical
Cabinet dimensions	Critical
Cooling	Critical
Motor parameters	Critical
Application duty	Critical
Installed options	Critical

A drive with similar horsepower can still be electrically incompatible.

41. Limitations

The 20DJ248A0NNNACGNE is not necessarily the best choice for every 200 HP motor.

Its large size, DC-bus architecture and high current rating can be excessive for simple applications.

For a small pump or fan, a much smaller drive may be more economical.

For a simple fixed-speed motor application, a VFD may not be necessary at all.

For precision servo positioning, a dedicated servo system is generally more appropriate.

For a new project, engineers should also consider whether a newer drive platform offers better lifecycle support, communications and maintenance capabilities.

For an existing 20D installation, however, maintaining the same drive family can be advantageous because it may minimize changes to the machine-control architecture.

43. Final Summary

The 20DJ248A0NNNACGNE is a high-power PowerFlex 700S, 20D-series industrial AC drive intended for demanding motor-control applications.

Its key electrical rating is 248 A continuous output, with approximately 273 A available for one minute and 372 A for three seconds. It is a 650 VDC input, Frame 6 configuration and is rated for approximately 200 HP normal duty or 150 HP heavy duty.

The approximately 132 kW normal-duty rating makes it suitable for substantial industrial motors.

The 150 HP heavy-duty rating is particularly relevant to applications with greater torque and overload requirements.

The drive’s main strength is not simply its current capacity.

Its combination of high-power output, common DC-bus architecture and high-performance motor-control platform makes it suitable for sophisticated industrial systems.

Typical applications include large conveyors, mining and bulk-material handling, pumps, fans, blowers, compressors and process machinery.

For conveyors, controlled acceleration can reduce mechanical stress.

For pumps and fans, variable-speed control can improve process regulation and potentially reduce energy consumption.

For multi-drive systems, the DC-bus architecture can provide a useful common electrical platform.

The drive’s published power-loss figure is approximately 2115 W, so cabinet thermal management is an important engineering consideration.

The 20DJ248 belongs to a useful progression of 650 VDC PowerFlex 700S drives.

The 20DJ125, 20DJ156 and 20DJ180 provide lower current capacities, while the 20DJ261, 20DJ300 and 20DJ385 provide progressively higher capacities.

For mechanical installation, the drive is a Frame 6 unit.

The exact dimensions and weight should be taken from the applicable Frame 6 mechanical configuration rather than assuming that every catalog variation has an identical physical package.

For this reason, the dimensional and weight fields above are deliberately marked as configuration-dependent where an exact value could not be established reliably.

Overall, the 20DJ248A0NNNACGNE is best suited to large industrial motor systems where 248 A continuous current, 200 HP normal-duty capacity, 650 VDC common-bus operation and advanced drive control are required.

For an existing installation, the complete catalog number should be preserved.

Before replacement, the motor current, duty rating, DC-bus arrangement, braking requirements, feedback hardware, communication architecture, cabinet dimensions and cooling system should all be checked.

For a new installation, the 20DJ248 should be compared against the required motor current and application duty rather than selected solely from the nominal horsepower figure.
