IS200EPSMG1A GE - Power Supply Module

GE IS200EPSMG1A Exciter Power Supply Module Overview

The General Electric IS200EPSMG1A serves as a vital Exciter Power Supply Module (EPSM). This component is a key part of the EX2100 Excitation Control System. It provides regulated power to the control assemblies and various external modules. The module ensures reliable operation for turbine control and excitation functions.

Technical Specifications

• Brand: General Electric (GE)

Core Functions and Design

• The module features a two-stage power conversion design for high efficiency.
• A buck-regulator first steps the input down to an intermediate 50 V DC level.
• A push-pull inverter then generates the final isolated output voltages.
• This design provides high-voltage isolation between the input and the control system.
• The IS200EPSMG1A specifically belongs to the EPSM Group 1 (EPSMG1) family.
• It delivers logic-level power to the M1, M2, and C controllers in the system.

Installation and System Integration

• Install the module directly into the Exciter Power Backplane (EPBP).
• The EPBP is located beneath the Exciter Backplane (EBKP) in the control cabinet.
• Connectors P1 and P2 transfer power from the module to the backplane.
• Each controller uses three independent IS200EPSMG1A modules for power.
• The module works in conjunction with the Power Distribution Module (EPDM).

Power Delivery and Applications

• The module supplies +5 V DC, ±15 V DC, and 24 V DC to the control assembly backplane.
• It provides 24 V DC to power external components like fans and the crowbar module.
• An isolated +70 V DC output is dedicated for terminal board contact wetting.
• This ensures reliable operation for the ECTB and EXTB terminal board modules.
