GE IS200AEPAH1BDB Board Industrial Control Module
Description
GE IS200AEPAH1BDB is an exciter power amplifier board (AEPA) designed to maintain operation of GE Mark VI/VIe gas and steam turbines when lower-cost power stages fail. It features a self-contained H-bridge with IGBTs, gate drivers, current sensors, and a 16-bit control DAC, communicating with Mark VIe controllers via internal CAN/RS-485 links, and a fiber optic status port for real-time operational reporting.
