GE IS200EHPAG1ADC Gate Pulse Amplifier Board

Overview

The GE IS200EHPAG1ADC is a gate pulse amplifier board for GE EX2100 excitation systems. It controls silicon-controlled rectifiers (SCRs) by amplifying gate pulses with high precision. The board receives commands from the ESEL board and converts them into reliable triggering signals. Additionally, it monitors SCR conduction using real-time feedback to enhance safety and performance.
