Fuji Electric DES100A Power Supply Repair Service

Professional diagnostic and board-level repair service for this Fuji Electric DES100A Power Supply.

The Fuji Electric DES100A is a compact servo drive controller used for motion‑control applications such as CNC machines and packaging equipment. Common failure points on this model include the power supply section (MOSFETs or IGBT modules), the main control board’s ICs (e.g., DSP/CPU), and the input/output interface circuitry; overheating, voltage spikes, or aging capacitors often cause erratic behavior or complete shutdown. For initial troubleshooting, verify that the 24 V DC power supply is within spec, inspect all connectors and solder joints for cracks or corrosion, and check the diagnostic LEDs or error codes on the front panel to pinpoint whether the fault lies in the drive, I/O, or communication bus.
