Description / Overview
The GE IS200EDEXG1AFA is a high-performance De-Excitation Board designed for the EX2100 Excitation Control System, widely used in gas, steam, and hydro turbine generators. It ensures safe generator shutdown by rapidly dissipating residual field energy when excitation is removed.
This board integrates SCR-based de-excitation with conduction sensing and voltage protection, maintaining system stability and protecting equipment from overvoltage conditions. Moreover, Hall effect sensors monitor current flow, while diagnostic feedback enables real-time system health monitoring.
Compact and panel-mounted, the IS200EDEXG1AFA is engineered for reliable operation in demanding industrial environments, offering seamless integration into existing EX2100 systems. Its lightweight design and precision control logic ensure efficient energy dissipation while maintaining operational safety.
