IS200EPSMG1AED Overview

The General Electric Exciter Power Supply Module IS200EPSMG1AED is an Exciter Power Supply Module for the EX2100 series. It features three 125 VDC trip solenoids, six analog voltage inputs, and supports reliable operation in temperatures from 0 to 60°C.

Product Features

• Emergency Trip Terminal Board: Acts as a key safety module in the EX2100 Excitation Control System.

• Power Conversion Design: Integrates a buck regulator and push-pull inverter for stable multi‑voltage output.

• High Isolation Safety: Transformer‑based inverter ensures complete isolation between input and control outputs.

• Dedicated Application: Designed specifically for the Exciter Power Supply (EPSM) Group 1 in excitation control systems.

Application

• System Role: Converts 125 VDC from PDM into control voltages for the EX2100 excitation control system.

• Redundant Power Supply: Three independent EPSMG1 modules provide power to controllers M1, M2, and C respectively.

• Mounting & Distribution: Installed in the Exciter Power Backplane (EPBP); power is delivered via connectors P1/P2 to backplanes and external modules.

• Output Voltages: Supplies +5VDC, +15VDC, and +24VDC to the control assembly backplane.

• External Power Supply: Provides +24VDC to fans, de-excitation, crowbar, ground detector, and measurement modules; also offers isolated +70VDC for contact wetting on terminal boards.
