Product Introduction

The GE IS200EPSMG2A is an Exciter Power Supply Module designed for integration into GE’s Mark VI and Mark VIe excitation control platforms. This module plays a vital role in supplying regulated low-voltage DC power to various control and interface components within a synchronous generator excitation system.

As part of the exciter control infrastructure, the IS200EPSMG2A is responsible for converting AC input power into multiple stable DC outputs used to energize terminal boards, signal processors, communication modules, and system relays. The module features high-efficiency switch-mode power conversion and multiple built-in protection mechanisms, ensuring long-term operational stability even in demanding industrial environments.

Its compact form factor and plug-in design allow for quick installation, minimal downtime during maintenance, and seamless integration into existing GE turbine control cabinets. The EPSMG2A is well-suited for both new builds and system upgrades across a wide spectrum of industrial and power generation applications.
