The IS200EPDMG1B module is another Exciter Power Distribution Module. This is the second version of the IS200EPDM module, this module is just one of the power supply boards in the EX2100 series. As many of the other power supply modules will be connected to this board the toggle switches on the board can cut power consumption from the other power supply boards. When you have cut power consumption to the other board the LEDs that line up with the other board will turn off, to indicate that the power has been switched off.
The IS200EPDMG1B board provides a power supply for the other boards such as the protection, control, and I/O terminal boards. The standard power supply for the EPDM board will be a VDC of 125 or a VAC of 115. On the board, there are twelve plug connectors; two of the connectors are twelve-position, nine are two-position plugs, and one is a three-position plug, all of the connectors are female connectors.
The IS200EPDMG1B also has nine metallic oxide varistors which are all grouped together in a quadrant at the bottom of the board. The outputs that come from the EPDM board can be supplied to EGPA, EPSM, and EXTB boards.
