Description
xFANUC A02B‑8100‑0851 is a power supply printed circuit board (PCB) used in industrial FANUC CNC controller systems. Despite the variation in your spelling (FANUC parts often start with either A20B or A02B), this part specifically refers to the power module of the controller electronics.
🔌 What It Does
-
Power Supply Module: The A20B‑8100‑0851 board provides stable and regulated DC power to the CNC controller’s internal electronics — including CPU boards, display modules, motion cards, and I/O interfaces.
-
Controller Role: It’s a critical infrastructure component inside FANUC CNC cabinets (e.g., older i‑Series and other industrial control models), enabling the control electronics to power up, operate stably under load, and handle varying industrial power conditions.
-
Form Factor: A PCB that mounts into a controller backplane or power section — usually near the main processor and axis control boards.
