ABB 3BHB000652R0001ABB 3BHB000652R0001 (KUC720AE01) Full Product Information
ABB KUC720AE01 3BHB000652R0001 Excitation Control Power Board / Converter Control Motherboard Core Function This circuit board is a dedicated power & excitation control module for ABB industrial DC drives and static excitation systems for synchronous generators. It converts AC mains input into stabilized multi-channel DC power for drive internal logic, gate drive circuits, and field excitation regulation. It integrates current sampling, voltage feedback, fault detection, and RS485/Modbus communication to deliver closed-loop excitation control, overcurrent/overvoltage protection, and real-time drive status monitoring for power plant generator excitation units and heavy-duty industrial DC motor drives. It executes PWM excitation regulation and transmits operational data to upper ABB DCS/800x
