The FANUC A20B-2100-0761 is a control PCB for selected FANUC αi common power supply modules. FANUC assigns it to the 200V PSM-26i through PSM-55i range and 400V PSM-30HVi through PSM-75HVi range.
This is an internal PCB, not a complete power supply. Confirm its label, revision, host A06B number, connectors and original board before ordering.

αi Power Supply Control Function
Installed in the PSM, the A20B-2100-0761 provides control and monitoring circuitry for the common power supply and regenerative operation. Electrical ratings belong to the complete A06B module, not to the bare PCB as a standalone device.
Old and Later Board Specifications
Later FANUC documentation lists A20B-2100-0391 as the current specification and A20B-2100-0761 as the old specification for corresponding A06B-6110 and A06B-6120 modules. Confirm the complete module number, PCB revision and service documentation before substitution. Do not confuse it with A20B-2100-0760 for smaller PSM models or A20B-2100-0390 for different configurations.
Testing and Installation Notes
REACO CNC checks the label, revision, fuses, connectors, solder condition, control power, status display, alarms and startup as applicable. Qualified personnel should isolate power and wait for the DC link to discharge before service.
