FANUC A17B-2100-0744 is an internal power supply board unit / servo amplifier power board for compatible FANUC CNC drive equipment. The assembly combines a printed circuit board, heat sink, power modules, DC-bus capacitors, relays and high-current terminals used in the drive power stage.
This product is supplied by its exact board number, A17B-2100-0744. It is not a CNC CPU board or a complete A06B drive. Confirm the original A17B marking, complete A06B model, PCB revision and physical layout before replacement.

Power-Stage Function
The A17B-2100-0744 forms part of the drive power stage. Its modules switch current under control of the amplifier circuitry, while the capacitors, relays, bus connections and heat sink support power conversion and thermal management. Electrical ratings are determined by the complete FANUC drive, not by this internal board number alone.
Compatibility and Revision Checks
Match A17B-2100-0744 exactly and compare every revision suffix printed on the PCB. Verify the complete drive model, module arrangement, terminal labels, connectors, heat-sink design, mounting points and installed components. Similar A17B-2100 boards are not automatically interchangeable.
Testing and Installation
REACO CNC checks the board marking, capacitors, relays, power modules, terminals, connectors, solder joints, insulation and signs of heat damage, followed by functional testing where applicable. Qualified personnel should isolate power and allow the DC bus to discharge fully before installation.
