Ablecom SP645-PS Switching Power Supply Repair Service

Professional diagnostic and board-level repair service for this Ablecom SP645-PS Switching Power Supply.

The Ablecom SP645‑PS is a 645 W switching power supply rated for 100–240 V input, commonly used in industrial control cabinets and high‑power server environments. Common failure points for this model include degraded MOSFETs or IGBTs, burnt-out capacitors on the output side, fan motor wear, and over‑temperature shutdown due to inadequate ventilation. First‑check diagnostics: verify incoming AC voltage with a multimeter; inspect the unit for visible burn marks, swollen electrolytics, and fan operation; measure output rails (12 V/5 V/3.3 V) under load and check for ripple or dropout; review any built‑in diagnostic LEDs or error codes if present.
