General Electric IS200EPSMG1A EX2100 Exciter Power Supply Module

The EPDM provides power for the control, I/O, and protection boards. It is mounted on the body of the EPBP and accepts a 125 V DC supply from the station battery, and one or two 115 V AC supplies. All power inputs are analog. Each AC supply is regulated to a 125 V DC supply via an AC-DC converter (DACA). The two or three DC voltages generated are coupled together differentially to form DC power sources, named P125V and N125V. Due to the center ground, the ground values ​​of these voltages are +62.5 V and -62.5 V to ground. The individual power supply outputs provided to the excitation board are fused. They have an on/off toggle switch, and a green LED spindle to show the power supply availability. These outputs can supply up to three EGPA boards, one EXTB board, and three EPSM modules serving three controllers.
