IS200EPDMG1ABA Exciter Power Distribution Module
The IS200EPDMG1ABA Exciter Power Distribution Module (EPDM) is used in the EX2100 Excitation Control to provide power for the control, I/O, and protection boards. It is mounted on the side of the IS200EPBP Exciter Power Backplane (EPBP), receives 125 V dc power from the station battery, and accepts one or two 120 V ac power inputs for backup. All power supply inputs, which are filtered, are received through a board-mounted terminal block (TB1). Each ac supply is rectified to 125 V dc in an external ac-to-dc converter (DACA or DACB). The resulting two or three dc voltages are diode-coupled through external diodes to create the dc source power supply, designated P125V and R125V. These voltages are center grounded and are nominally +62.5 V and –62.5 V to ground. The module is chassis grounded and safety-grounded through four of the board mounting holes. The tables below provide current information.
Two 12-plug connectors (JDACA1 and JDACA2) connect the ac power sources from the terminal block (AC1 and AC2) to the external DACA#1 and DACA#2, and return the DACA outputs to the 125 V dc lines (P125 and R125).
Individual power-supply outputs to each of the exciter boards are fused, have an on/off toggle switch (except the EXTB board), and a green LED indicator to show power availability. The outputs supply up to three IS200EGPA Exciter Gate Pulse Amplifier Boards (EGPA), the IS200EXTB Exciter Terminal Board (EXTB), and three IS200EPSM Exciter Power Supply Modules (EPSM) serving three controllers. A separate connector is provided for each output; these are wired to the EPBP for distribution.
