Core Specifications
Input Type: Single-phase AC input, suitable for common industrial AC power supply environments.
Output Parameters: DC output voltage is 56V, with an output power of 1500W, which can fully meet the power requirements of the drive’s control circuit and associated components.
Compatible Equipment: Specifically designed for the PowerFlex 7000 series medium-voltage AC drives (including models 7000A, 7000, and 7000L, corresponding to Frame A, Frame B, Frame C, as well as marine, heat pipe and other types of drives), featuring high compatibility.
Component Part Number: The official standard part number is 80026-524-01-R. It is an original spare part certified by Rockwell Automation, ensuring perfect compatibility with the equipment.

Functions & Application Scenarios
Fault Protection Compatibility: Integrates with the drive’s fault detection system. In the event of abnormal output from the power supply module, it will trigger relevant fault codes of the drive system (e.g., AC/DC power supply fault codes), facilitating quick troubleshooting.

Troubleshooting & Maintenance Recommendations
Verify that the input AC voltage of the power supply module (typically 110Vac or 120Vac) is stable and meets the rated input requirements.
Measure the module output voltage to confirm it reaches the standard value of 56V; a voltage below 49Vdc may trigger a DC Fail fault.
Inspect the connection lines between the module and the Analog Control Board (ACB) for firmness and ensure normal signal transmission.
Check the operation status of the internal cooling fan of the module. If fan failure causes module overheating, replace the fan or the module itself promptly.
