Product Description

The IS200EHPAG1ADC is a specialized Gate Pulse Amplifier board engineered for the GE EX2100 excitation control system. Serving as the interface between the control logic and the power section, this module receives low-voltage firing signals from the ESEL logic board and amplifies them into high-voltage pulses. These pulses are used to trigger up to six Silicon Controlled Rectifiers (SCRs), which are essential for regulating generator field current and maintaining stable voltage output under dynamic load conditions.

Designed for reliability in harsh industrial environments, the IS200EHPAG1ADC features an extended operating temperature range of -30°C to +65°C. It integrates directly into excitation cabinets and supports critical system diagnostics. The board includes conduction feedback monitoring, which allows the controller to verify SCR firing in real-time, preventing misfires and ensuring the safe operation of steam, gas, and hydroelectric power generation assets.
