The 531X111PSHARG3 is a Motor field control and power supply board developed by GE. It is a part of the GE 531X system.

This card provides the necessary power supply for the drive. This component can also be used to power motor field electronics. The MOVs for the AC line are located externally rather than on the board because this is a G3 version of the board.

Features:
The power supply board's efficiency is necessary for drive operation.

Three power supplies with a 5 VDC, 15 VDC, and 24 VDC rating can be created with this device.

The motor field circuitry in the drive is powered by an integrated pulse transformer on the card.

The three onboard relays are used to control the devices. K1 (RUN), K2 (MAX), and K3 make up the trio (FAULT). On the PCB there are also three more potentiometers.
