Product Description
ABB UAC375AE103, order code 3BHB006621R0103, also known as Anti-Satur Board, is a dedicated control PCB for ABB large drives and high-power inverter systems. The board collects voltage and current feedback signals in real time. Built-in algorithm prevents magnetic saturation of transformers and reactors, avoiding current distortion, overheating and damage to power semiconductor devices caused by saturation. It adopts CPCI Eurocard form factor and connects via backplane bus, integrating signal acquisition, filtering, calculation and fault detection circuits.
