GE IS200EGPAG1BCA

Product Introduction: The IS200EGPAG1BCA is a gate pulse amplifier board (EGPA) in GE’s EX2100 excitation control system, designed to generate and amplify gate trigger pulses for six silicon-controlled rectifiers (SCRs) in the power bridge, enabling precise control of power conversion and distribution. It serves as a critical interface between the EX2100 controller and power bridge, integrating real-time monitoring of conduction current, airflow, and temperature (via RTD or CLICK switches) with built-in alarm/trip logic for over-temperature protection. It features 5 configurable jumpers, red/green LED status indicators, and industrial-grade components for reliable operation in power generation and heavy industrial environments, ensuring stable SCR triggering, feedback monitoring, and system protection.
