When selecting your next power entry filter or transient suppressor, remember that the initial savings of a generic component are quickly erased by downtime, troubleshooting hours, and premature equipment failure. By specifying DPHN 142, you invest in operational continuity and peace of mind. | Symptom | Possible Cause | Corrective Action

| Symptom | Possible Cause | Corrective Action | |---------|----------------|--------------------| | No output voltage; all LEDs off | No input power; blown internal fuse | Check upstream breaker; replace DPHN 142 (fuse is non-user-serviceable) | | Red LED steady on | Reversed input polarity | Swap L1 and N (or + and - for DC) | | Amber LED blinking | High leakage current due to moisture or damaged cable | Perform insulation resistance test; dry unit at 50°C for 4 hours | | Equipment resets randomly (intermittent) | Loose ground connection or terminal screw | Re-torque all connections; check PE continuity | | Green LED on but load not working | Broken internal inductor (rare) | Shake unit—if rattling, replace immediately | | Overheating (case >85°C) | Overcurrent beyond 10A per line; poor ventilation | Reduce load or add forced air cooling |
