FANUC A20B-1003-0890 Power Supply Board, CNC PCB Board

The FANUC A20B-1003-0890 is an original industrial-grade CNC power supply PCB board, serving as a core power distribution component for FANUC CNC servo and spindle drive systems. This board converts, regulates, filters, and distributes industrial power within CNC electrical cabinets, providing stable DC working voltage for servo amplifiers, control boards, and signal circuits.

By eliminating grid voltage fluctuations and power noise, it ensures continuous, stable power supply for the entire CNC control system. Widely used for faulty board replacement, maintenance, and equipment renovation of FANUC CNC lathes, machining centers, and automated machine tools, it resolves common issues like power failure, system startup failure, and servo alarms caused by damaged power boards.
