GE IS200EHPAG1BBA Exciter Gate Pulse Amplifier Board

Description

The GE IS200EHPAG1BBA is a high-reliability Gate Pulse Amplifier Board used in GE’s EX2100 and EX2100e excitation control systems. It receives fiber-optic gate command signals from the ESEL logic board and amplifies them to trigger six Silicon-Controlled Rectifiers (SCRs). With built-in diagnostics and environmental monitoring, it ensures precise control and protection of high-voltage power conversion systems.
