Product Details

ABB UFC718AE101 HIEE300936R0101 is a main circuit interface board used for ABB UNITROL generator excitation system and AC800PEC power electronic controller. The main circuit interface board serves as the signal bridge between the excitation controller and high-power power circuit, completing signal conditioning, gate drive signal distribution, and real-time voltage and current feedback signal acquisition. This ABB UFC718AE101 board converts control commands from the main controller into drive pulses for power semiconductor devices, and feeds collected generator feedback signals back to the main controller for closed-loop excitation regulation. The power electronic control board adopts conformal coated circuit design, featuring strong anti-electromagnetic interference capability to adapt to harsh working conditions inside power plant excitation cabinets. It continuously monitors internal circuit and signal wiring status, and outputs fault alarm signals when abnormal connection or circuit failure occurs. It supports high-speed fiber optic communication to realize fast real-time data exchange with the main control unit. Widely used in thermal power, hydropower generator excitation control cabinets, it is a critical spare part for maintenance and renovation of UNITROL excitation systems. Rack plug-in design supports quick installation and field replacement.
