IS200EPSMG2AED

Overview

The IS200EPSMG2AED is an Exciter Power Distribution Module from General Electric, part of the EX2100 control system. It is integral to both the EX2100 Excitation Control System and the EX2100 Regulator Control, where EPSM Group 2 modules (EPSMG2) are used, featuring an additional EPSD Exciter Regulator Power Supply Daughter board.

Specifications

• Product Type: Exciter Power Distribution Module

• Operating Temperature: -30°C to +65°C

• Part Number: IS200EPSMG2AED

• Manufacturer: General Electric

Composition and Functionality

• Buck-Regulator:

• Lowers input voltage to an intermediate 50 V DC.

• Regulates output by adjusting the duty cycle of a switching element (e.g., transistor or MOSFET).

• Push-Pull Inverter:

• Converts the 50 V DC to multiple output voltages for system components.

• Uses a pair of transistors in a push-pull configuration for efficient AC generation.

Key Features

• Fuse Protection: Includes a 600 V, 5 A fuse (FU1) for current protection.

• Testpoints: 13 testpoints for monitoring voltage outputs (PCOM, DCOM, ACOM, ICOM).
