Exciter Power Assembly Module IS200AEPAH1BEB(IS215WEPAH2BA) by GE
Description
Exciter Power Assembly Module IS200AEPAH1BEB(IS215WEPAH2BA) is a robust exciter power amplifier board designed by GE Vernova to support stable operation of GE Mark VI/VIe gas and steam turbines under complex working conditions. It delivers regulated excitation current from a 24Vdc bus to prevent issues caused by high ambient temperatures, blocked cooling fans, or brush gear arcing, maintaining turbine performance and grid stability.
