The GE IS200EPSMG1AEC is an Exciter Power Supply Module integral to the EX2100 excitation system. It converts 125V DC input from the EPDM into multiple output voltages to power controllers and associated interface boards.

It also provides 70V DC for contact wetting on EXTB and ECTB boards. Designed for redundancy, it supports independent power distribution to controller sections, ensuring system stability during single module issues. With robust overcurrent protection, it operates reliably in industrial environments, facilitating consistent signal processing and communication within the excitation system.
