GE IS200EPSMG1A IS200EPSMG1ADC |Power Supply Module

Technical Overview of the GE IS200EPSMG1A IS200EPSMG1ADC for Mark VI

The GE IS200EPSMG1A IS200EPSMG1ADC converts AC input into stable DC voltage. This module belongs to the Mark VI series from General Electric. It specifically serves the EX2100 exciter control lineup. Therefore, it provides clean power to field flashing and regulation boards.

Compact Dimensions and Lightweight Construction

This power supply module measures 15 cm in width, 12 cm in height, and 3 cm in depth. The GE IS200EPSMG1A IS200EPSMG1ADC weighs approximately 0.35 kg, which eases rack mounting. Its single-board design uses high-grade FR4 material. Consequently, you can install it without extra reinforcement.

Input and Output Interfaces

The GE IS200EPSMG1A IS200EPSMG1ADC features one 3-pin AC input terminal block. It also provides two 4-pin DC output connectors for load distribution. This module contains six discrete rectifier diodes for AC-to-DC conversion. Additionally, it includes three large filter capacitors for energy smoothing.
