Overview

The GE IS200EHPAG1BBA is a high-reliability exciter gate pulse amplifier designed for GE’s EX2100 excitation control platform. It amplifies gate pulse signals from the ESEL logic board and drives six silicon-controlled rectifiers (SCRs) in the power bridge. These SCRs regulate the generator’s field current, ensuring stable voltage output and safe operation under dynamic load conditions.

Additionally, the board includes several monitoring features such as conduction current feedback, airflow, and temperature sensing. These features help prevent issues like misfires, overheating, and electrical faults, contributing to system safety and operational continuity. Its compact, rack-mounted design allows for easy integration into excitation cabinets, making it suitable for both new installations and retrofit projects.

This board is widely used in steam, gas, and hydroelectric power plants, where precise SCR control is crucial for generator protection and performance.

Technical Data

Typical Applications

• Generator Excitation Systems: Ensures precise SCR control and fast response for field current regulation.

• Power Bridge Interfaces: Works in EX2100 excitation cabinets to interface between the controller and SCRs.

• Fault Monitoring & Thermal Protection: Monitors system health to prevent overheating and electrical anomalies.
