ABB 3BHE006412R0101ABB UNITROL Series Field Current Measurement & Excitation Limiter PCB Assembly
High-precision sampling of generator rotor field current and voltage from thyristor rectifier bridge, converting raw power analog signals into isolated low-level digital signals. Executes hardware-based excitation limit protection including maximum field current limiter, rotor thermal overload protection, and under-excitation reactive power boundary control. Provides galvanic isolation between high-voltage power circuits and low-voltage control logic to suppress EMI and surge transients. Real-time feedback closed-loop regulation for automatic voltage control and power factor adjustment.
