IS200EPDMG1BAA GE EX2100, Exciter Power Distribution Module

Description:

IS200EPDMG1BAA is an exciter power distribution module, manufactured by GE. IS200EPDMG1BAA belongs to IS200EPDM. 

The IS200EPDM Exciter Power Distribution Module (EPDM) is used in the EX2100 Excitation Control to provide power for the control, I/O, and protection boards of the exciter. It is mounted on the side of the IS200EPBP Exciter Power Backplane (EPBP) and 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 are received through a board mounted terminal block (TB1) and are filtered. Each ac supply is rectified to 125 V dc in an external Ac to Dc Converter (DACA). 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.
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 and these are wired to the EPBP for distribution.


Frequently Asked Questions:
1.What is the current and voltage for IS200EPDMG1BAA requirement?
All connectors are rated 600 V ac or dc. The terminal board is rated 300 V (10 A per pin); all switches are rated 125 V dc, 6 A.

2.What is the primary function of the Exciter Power Distribution Module (EPDM)?
The module serves as a critical component in excitation control systems, providing power distribution for control, I/O, and protection boards within the exciter.

3.What are the connectivity options offered by the module?

Equipped with a 24-point terminal block and ten plug connectors, the module provides ample connectivity options rated at 600 V ac or dc, ensuring safe and reliable connections for various system components.
