Overview
The GE IS200EHPAG1ADC is a gate pulse amplifier board integral to GE's EX2100 excitation control system. It amplifies gate pulses received from the ESEL logic board, converting them into high-voltage pulses that trigger up to six silicon-controlled rectifiers (SCRs). These SCRs regulate the generator field current, maintaining stable voltage output and enabling safe operation under varying load conditions.
The EHPAG1ADC board also includes conduction feedback monitoring and supports high-speed communication with the controller. Built for high-voltage industrial environments, it integrates seamlessly into excitation cabinets and contributes to system diagnostics and protection, preventing misfires and overheating.
This module is primarily used in steam, gas, and hydroelectric power plants, where precise SCR control and excitation reliability are crucial.
