IS200EPDMG1BAA GE Exciter Power Distribution Module

Description

The GE IS200EPDMG1BAA Exciter Power Distribution Module is a vital component within the EX2100 excitation system, part of the Mark VI series. It functions as the central hub for distributing electrical power to various subsystems, including control processors, I/O boards, and protection circuits. By managing both AC and DC inputs, it ensures uninterrupted and conditioned power delivery across the excitation cabinet. Moreover, the EPDM module supports dual input sources-125 VDC from station batteries and up to two 120 VAC lines-for redundancy and fault tolerance. In addition to power routing, it provides fuse protection, filtered inputs, and LED status indicators for diagnostics. Its compact, rack-mounted design simplifies installation and maintenance in high-density control environments. Therefore, the IS200EPDMG1BAA is widely used in gas, steam, and hydroelectric power plants where stable excitation power is critical for generator performance and safety.
