GE IS200EBACG2ABA EX2100E Excitation Bridge AC Feedback Board

Product Description

Model: IS200EBACG2ABA, GE Speedtronic Mark VI EX2100E Exciter Bridge AC Feedback Board (EBAC), a PCB card for gas turbine and generator excitation control system. It collects AC voltage and current feedback signals from excitation rectifier bridge, isolates and converts high-power analog signals to EX2100 excitation controller for closed-loop excitation current regulation, bridge condition monitoring and fault diagnosis. Equipped with signal conditioning, isolation circuits and connectors. It is a critical spare part inside EX2100E excitation cabinet. Original production discontinued, available stock mainly used or professionally refurbished & tested units.

Application

Used with GE Mark VI gas / steam turbine generator sets EX2100E excitation system. It acquires AC electrical parameters of excitation rectifier bridge in real time and feeds signals to excitation controller for generator closed-loop excitation regulation. It monitors bridge operating condition and detects overcurrent, phase unbalance and rectifier faults. Widely applied in combined cycle power plants, thermal power steam turbine and gas turbine power stations. Suitable for spare part replacement, unit overhaul, excitation cabinet retrofit and equipment troubleshooting.
