GE IS200EHPAG1BAA High-Speed Gate Driver Board for Mark VIe Control

Description

TheGE IS200EHPAG1BAAis agate pulse amplifier boarddesigned forGE’s EX2100andEX2100eexcitation control systems. Its main function is to receivefiber-optic gate commandsfrom theESEL logic boardand amplify them intohigh-voltage pulsesthat triggersix silicon-controlled rectifiers (SCRs). These SCRs are used to regulate the generator field current, maintaining stablevoltage outputand enablingsafe operationunder varying load conditions. In addition to its core amplification function, theEHPAG1BAAboard is equipped with several monitoring and protection features, including: Conduction feedback, Airflow and temperature sensing, Onboard diagnostics. These features help improve thesystem reliability, preventingmisfires,overheating, andelectrical faults. The board’scompact, rack-mounted designallows it to integrate easily intoexcitation cabinets. It is suitable for bothnew installationsandretrofit projects. This module is commonly used insteam,gas, andhydroelectric power plants, whereprecise SCR controlis crucial forgenerator performanceandprotection.
