GE IS200EHPAG1BAA Gate Pulse Amplifier Board

Description

The GE IS200EHPAG1BAA is a high-performance Gate Pulse Amplifier Board used in GE’s EX2100 and EX2100e excitation control systems. It receives fiber-optic gate command signals and amplifies them to trigger Silicon-Controlled Rectifiers (SCRs) in high-voltage industrial applications. With built-in diagnostics and environmental monitoring, it ensures precise control and protection of power conversion systems.
