Product Overview
The Allen Bradley 80026-044-06-R Switching Power Supply is a switching power supply component used to provide regulated electrical power for industrial automation equipment. In an automation cabinet, a power supply serves as the link between the available incoming electrical source and the DC power required by control-system components.
Switching power supplies are commonly used for control circuits because they can convert electrical power efficiently while maintaining a stable output under changing load conditions.
The 80026-044-06-R can be considered within the power architecture of an industrial control cabinet, supporting equipment such as control electronics, interface devices, sensors, and other DC-powered components.

Working Principle
A switching power supply converts the incoming electrical energy into a regulated output suitable for connected control equipment.
The basic power path can be represented as:
Input Power → Switching Circuit → Voltage Conversion → Regulation → DC Output
The switching circuit rapidly controls the transfer of electrical energy through the power-conversion stage. The converted output is then regulated so that the connected automation equipment receives a controlled power source.
Compared with a conventional linear supply, switching technology uses high-frequency switching to perform power conversion, allowing the power supply to achieve a compact form factor and efficient energy conversion.
In an industrial cabinet, the resulting DC power can then be distributed to the appropriate control and interface components.
Role in an Industrial Automation System
The power supply sits at the power-distribution layer of an automation system rather than the control-processing layer.
A simplified architecture is:
AC / DC Input → Switching Power Supply → DC Distribution → PLC / I/O / Sensors / Interfaces
The power supply therefore affects the operating stability of the equipment connected to its output.
| System Component | Power-Related Function |
|---|---|
| Switching Power Supply | Converts and regulates electrical power |
| PLC / Controller | Uses supplied power for control processing |
| I/O Modules | Receive operating power |
| Sensors | Receive required field power |
| Communication Equipment | Receives operating power |
| Relays / Interfaces | Use control-circuit power |
| Field Devices | Receive appropriate supply voltage |
The actual output requirements should always be matched to the electrical specifications of the connected equipment.
Industrial Applications
The 80026-044-06-R can be applied in various industrial automation environments where a switching power supply is required.
| Application | Typical Use |
|---|---|
| Factory Automation | Control cabinet power |
| Machine Control | PLC and interface power |
| Material Handling | Control-system power distribution |
| Packaging Machinery | Automation circuit power |
| Process Equipment | Instrumentation and control power |
| Motor Control Panels | Control-circuit supply |
| Production Lines | Distributed control power |
| Industrial Panels | DC power conversion |
| Equipment Upgrades | Replacement power supply |
| Maintenance Projects | Power-system restoration |
Power System Integration
A switching power supply should be selected based on the complete electrical load rather than as an isolated component.
A typical arrangement is:
Incoming Supply → 80026-044-06-R → DC Distribution → Control Equipment
Associated equipment may include:
- PLCs
- I/O modules
- Industrial sensors
- Relays
- Communication interfaces
- Operator interfaces
- Signal conditioners
- Control circuits
- Terminal blocks
- Circuit protection devices
When replacing an existing power supply, engineers should verify the input requirements, output voltage, output current, wiring arrangement, protection requirements, and total connected load before commissioning.
Installation and Maintenance
Before installation, verify that the power supply matches the electrical requirements of the existing control cabinet.
Important checks include:
- Confirm the complete model number.
- Verify input power requirements.
- Confirm required output voltage.
- Check the connected load.
- Verify output-current capacity.
- Inspect wiring and terminals.
- Check circuit protection.
- Confirm grounding requirements.
- Inspect ventilation around the power supply.
- Verify the DC output after installation.
If downstream equipment experiences intermittent resets or communication problems, the power supply should be included in the troubleshooting process. Check the output voltage under both normal and loaded conditions rather than checking only the unloaded output.

Technical FAQs
What is the Allen Bradley 80026-044-06-R used for?
The 80026-044-06-R is a switching power supply used to provide regulated electrical power for compatible industrial automation and control equipment.
Why are switching power supplies commonly used in automation cabinets?
Switching technology allows electrical power to be converted efficiently while maintaining a compact physical design. This makes switching supplies suitable for control cabinets where space and power efficiency are important considerations.
What should be checked before replacing the 80026-044-06-R?
Verify the input requirements, output voltage, output-current capacity, wiring configuration, connected load, circuit protection, and mounting arrangement. The replacement should satisfy the electrical requirements of the complete control system.
Can a power supply problem cause PLC or communication faults?
Yes. An unstable or insufficient power source can cause controllers, I/O modules, communication equipment, or other electronics to reset or operate abnormally. When troubleshooting intermittent system faults, the supply voltage should be checked under actual operating load.
