Product Description
The Allen-Bradley/Rockwell Automation 20-750-APS auxiliary power supply is a robust and reliable PowerFlex 750 series module providing 20W of regulated 28V DC power. It accepts 90-264V AC single or three-phase input (50/60 Hz) and delivers 24V at 30A. Featuring AP+, AP-, and Sh terminals, it's designed for PowerFlex 753 drives (all frame sizes) and PowerFlex 755 frame 1 drives, ideally connected to Port 8. The backplane-supported module includes power and status LEDs and complies with LVD, EMC, MD, and other industrial standards.
Is Your Device Showing These Signs?
The Allen Bradley 20-750-APS servo drive commonly experiences issues such as IGBT failures, capacitor degradation leading to DC bus undervoltage faults, and encoder feedback problems causing erratic motor behavior. Resolving these faults requires replacing damaged power components, recapping the DC bus section with high-quality capacitors, and troubleshooting/replacing the encoder or its communication cable. Firmware corruption is also a potential problem, necessitating a firmware reload or drive replacement. Overcurrent faults are addressed by inspecting the motor and wiring for shorts or ground faults, and adjusting current loop parameters.

Our Repair Process for the
20-750-APS
Our repair process for the Allen Bradley 20-750-APS servo drive begins with a comprehensive diagnostic evaluation to pinpoint the root cause of the failure. This evaluation includes a thorough inspection of IGBTs, capacitors, encoder feedback systems, and firmware integrity. Upon identifying the fault, we proceed with component-level repairs, which involve replacing damaged power components, recapping the DC bus section with premium capacitors, and repairing or replacing the encoder and its communication cable as needed. In cases of firmware corruption, we reload the firmware or replace the drive. Overcurrent faults are resolved by inspecting the motor and wiring for shorts or ground faults and adjusting current loop parameters. Each repaired drive undergoes rigorous testing to ensure it meets or exceeds original performance specifications before it is returned.
