GE IS200AEPAH1BKE & IS215WEPAH2BB Excitation Power Amplifier Board Set
GE IS200AEPAH1BKE and IS215WEPAH2BB are matched excitation power amplifier board assemblies for GE Speedtronic Mark VIe turbine & generator excitation control system. IS200AEPAH1BKE is the AEPA power amplifier PCB, IS215WEPAH2BB serves as the supporting WEPA interface board, working together to drive the generator excitation loop with power amplification and signal conditioning.
This pair of boards features built-in overcurrent, overvoltage and thermal protection, and supports TMR redundant configuration for critical power generation units. They receive low-level excitation command signals from the Mark VIe controller and convert them into high-power drive signals for the exciter, widely used as matched spare parts for gas turbine and generator excitation cabinets.
