FANUC A20B-2101-0390 Power Control Board (αi Series)

• Component Type: Power Control PCB (PSM Side Board)
• Series Compatibility: FANUC α i Series / α HV i Series
• Input Voltage: 400–480 V AC (High Voltage compatibility)
• Integrated Components: Onboard Noise Filter, 7-Segment Diagnostic LED, Fan Motor (A90L-0001-0441)
• Dimensions: 230 mm × 100 mm × 40 mm (9.05" × 3.93" × 1.57")
• Weight: 0.47 kg (1.26 lbs)
• Environmental Limits: Operating: 0°C to 45°C (32°F to 113°F) | Humidity: 20% to 95% RH
• De-energize the Cabinet: Ensure the main breaker to the CNC machine is fully powered off and locked out. Wait at least 10–15 minutes for the internal high-voltage capacitors on the DC bus to discharge completely.
• Verify Voltage Discharge: Use a calibrated multimeter to check the DC link terminal points (L+ and L-) to verify that residual voltage has dropped below safety thresholds (<50V) before removing the module cover.
• Inspect the Fan Assembly: This board depends on the attached A90L-0001-0441 fan to prevent thermal cutoff. Ensure the fan moves freely and is clear of machining grease/debris during installation.
