Product Details

ABB KUC720AE01 and KUC755AE105 are matched power control rack modules for ABB AC800PEC power electronic platform and UNITROL generator excitation systems. The power control rack module set consists of core processing unit and power signal interface unit. KUC720AE01 executes real-time closed-loop power control algorithms, collects voltage and current feedback signals. KUC755AE105 handles power signal conversion, pulse distribution and backplane communication to coordinate the whole rack control logic. This matched ABB module set adopts reinforced galvanic isolation design to separate low voltage control circuits from high-power conversion circuits, effectively suppressing surge and electromagnetic interference in power plant cabinets. Built-in self-diagnostic function and LED status indicators monitor rack power status, fiber communication links and channel faults, and trigger alarm signals for fast troubleshooting. Conformal coated circuit board provides good resistance against moisture, dust and vibration, maintaining stable long-term operation under harsh industrial conditions. Widely used in power plant generator excitation cabinets, medium voltage converters and metallurgy high-power power conversion equipment, it is critical spare part for power electronic system maintenance, upgrade and renovation. Rack plug-in structure enables convenient installation and quick field replacement.
