Specifications

Description

IS200EPDMG1B is an Exciter Power Distribution Module developed by GE under EX2100.It is employed in the EX2100 Excitation Control to supply power to the exciter's control, I/O, and protection boards. It is located on the side of the Exciter Power Backplane (EPBP) and is powered by one or two 120 V ac inputs in addition to the station battery's 125 V dc output. A board-mounted terminal block(TB1) serves as the entry point for all power supply inputs and filters them. In an external AC to DC converter, each ac supply is rectified to 125 V dc (DACA). The resulting two or three dc voltages are connected together using external diodes to provide the P125V and R125V dc source power supplies. These voltages are nominally +62.5 V and -62.5 V to the ground and are center grounded.

Features

1 Safety Grounding: The module is safety grounded and chassis grounded through four mounting holes on the board.

2 DACA Connections: External DACA#1 and DACA#2 are connected to the terminal block’s AC1 and AC2 via two 12-plug connectors (JDACA1 and JDACA2).

3 DACA Output: The DACA outputs are connected to the 125 V dc lines (P125 and R125).

4 Fused Power Supply Outputs: Except for the EXTB board, each exciter board power supply output is fused, has an on/off toggle switch, and a green LED to indicate power availability.

5 Power Distribution: Three EGPA boards, EXTB board, and three EPSMs feeding three controllers receive power from the outputs, each via its own connector attached to the EPBP.

Application Data

1.A 24-point terminal block, ten plug connectors, seven switches, fourteen fuses, four grounded mounting holes, eight LED indicators, and a single adjustable jumper are all parts of the EPDM module. Each connector has a 600 Vac or dc rating.

2.All switches are rated at 125 V dc,6 A, but the terminal board is rated at 300 V(10 A per pin). On systems with external reference, the adjustable jumper (BJS) isolates the ground reference.

Replacement Procedures

1. Check if the exciter has been de-energized

2.Check that the power is off before touching any electrical circuits by opening the control cabinet door and usina hiah voltaae testina eauipment.

3. Take note of every switch's location on the board, then turn them all off

4. Carefully detach every cable connector from the board and remove it from the EPDM module.To make reconnection easier, ensure all wires are identified with the

correct connector name (as indicated on the board).
