I-Star Computer Co. TC-500 Power Supply Repair Service

Professional diagnostic and board-level repair service for this I-Star Computer Co. TC-500 Power Supply.

I-Star TC‑500 is a 500 W industrial switching power supply used in control panels and motor drives. Common failures include overheating of the internal MOSFETs or IGBTs, degradation of the output capacitors, and damage to the protection circuitry (over‑voltage, over‑current, short‑circuit). Typical symptom patterns are intermittent shutdowns when load exceeds 130 %–160 %, sudden loss of +5 V rail, or audible fan noise from thermal stress. First‑check diagnostics: verify input voltage and polarity; measure output rails (+12 V, +5 V) with a multimeter while the unit is powered on; inspect for burn marks, swollen electrolytics, and confirm that the over‑voltage and short‑circuit protection relays are not tripped or damaged.
