Torwico TW-7228 Control Unit Repair Service

Professional diagnostic and board-level repair service for this Torwico TW-7228 Control Unit.

Torwico TW‑7228 is a high‑current industrial power supply used in motor drives and control panels, typically providing 3 A output on three phases (ABC). Common failure modes for this class include overheating of the internal transformer or rectifier diodes, burnt capacitors on the DC bus, and degradation of the cooling fan or heat sink. First‑check diagnostics: verify input voltage and polarity with a multimeter; inspect the power supply enclosure for burn marks, swollen electrolytics, and fan operation; then test output rails (phase voltages) against spec while monitoring temperature rise.
