| Symptom | Likely Cause | Solution | | :--- | :--- | :--- | | | No input voltage or input fuse blown | Check mains supply (L-N). Test continuity of external fuse. | | Output voltage fluctuating (22-26V) | Overload condition (exceeding 6.3A) | Remove loads one by one. Measure total current with a clamp meter. | | Unit clicking rapidly / hiccup mode | Short circuit on the DC output | Inspect downstream wiring for chafed insulation or a failed capacitor. | | Red LED illuminated | Over-temperature or over-voltage | Allow unit to cool. Check ambient temp. Cycle power. | | Audible high-pitch whine | Light load or PFC (Power Factor Correction) frequency | Normal for many switching supplies. Add a 10-20% dummy load if desired. | Here is a competitive benchmark against generic market
