Protek PU110-4
 |
The Protek PU110‑4 is a compact, open‑frame AC‑DC switching power supply rated at 72–110 W continuous output with either forced or convection cooling. Common failure modes for this class include degraded electrolytic capacitors on the primary side, burnt-out MOSFETs or diodes in the rectifier/boost stages, and overheating of the internal heatsink causing thermal shutdown. Begin troubleshooting by verifying input voltage stability and ensuring the unit is properly ventilated; then check output voltage with a multimeter under load, inspect for visible burn marks or swollen capacitors, and review any error LEDs or fault codes displayed on the front panel.[oss-gpt-20b] |
