IS200EPSMG2A - EPSM Exciter Power Supply Module | GE EX2100 | B7B

IS200EPSMG2A is a General Electric EPSM Exciter Power Supply Module for GE EX2100 excitation control systems. In the EX2100 control cabinet, the EPSM converts 125 V dc supplied by the EPDM into the regulated voltages needed by the controller and terminal boards mounted in the EPBP power backplane.

The GEH-6632G EX2100 user guide describes the EPSM as producing +5 V dc, +/-15 V dc, +24 V dc, auxiliary +/-24 V dc, and isolated +70 V dc outputs, interfacing to the EPBP through DIN connectors; in redundant control, three EPSMs independently supply the M1, M2, and C controllers. For maintenance, repair, and spare-part planning, IS200EPSMG2A is an important replacement power supply module when supporting EX2100 excitation control cabinets, redundant or simplex control architectures, and turbine-generator excitation system reliability.

Control system parts are provided by GTC Control Solutions, Inc., a wholly owned subsidiary of B7B. Parts are offered in unused, repaired, or remanufactured condition, subject to availability. Each repaired or remanufactured component undergoes functional testing in energized panels, with test reporting and warranty support provided for repair and lifecycle-extension programs.
