The GE 531X111PSHARG3 is a power supply module used in General Electric turbine control and drive systems. Its primary function is to convert incoming AC or DC input into stable DC output voltages for the system backplane and associated modules. Built for demanding industrial environments, it is engineered for high reliability and continuous operation. The unit typically incorporates protective features such as overvoltage, overcurrent and short-circuit safeguards to support long-term equipment safety. The “HARG3” suffix identifies a specific hardware revision or configuration within the 531X series, indicating particular compatibility or performance characteristics.

Q: What is the 531X111PSHARG3?
A: It is a motor field control and power supply board, part of GE’s 531X series replacement boards.

Q: What systems use this board?
A: It is often used in GE excitation / drive systems (e.g. EX2000 excitation) and in generator / turbine control systems.

Q: What does the “G3” suffix indicate (PSHARG3)?
A: The “G3” revision indicates that the MOVs (metal-oxide varistors) for the AC line are mounted externally (i.e. not directly on the board).
