IS200EPDMG1B - EPDM Exciter Power Distribution Module | GE EX2100 | B7B

IS200EPDMG1B is a General Electric EPDM Exciter Power Distribution Module for GE EX2100 excitation control systems. In the EX2100 control cabinet, the EPDM accepts ac/dc control power sources and diode-couples the dc voltages into a P125V/N125V control power source feeding the EGPA/EHPA gate pulse amplifiers, EXHS board, and up to three EPSM modules.

The GEH-6632G EX2100 user guide describes the EPDM as accepting 125 V dc station battery power plus one or two 115 or 220 V ac supplies, with screw terminals for the battery and AC1/AC2 inputs and fused, switched, LED-indicated outputs; the source specifically notes that revision B or later of the EPDM is required to support 220 V ac control power sources. For maintenance, repair, and spare-part planning, IS200EPDMG1B is an important replacement power distribution 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.
