6.1 일반적인 결함, 원인 & 솔루션
| 결함 현상 | 가능한 원인 | 솔루션 |
| Abnormally low output voltage | 1. Excessive forward voltage drop of internal diodes | 1. Verify input voltage within 0~30VDC |
| 2. Insufficient input voltage | 2. Check and retighten terminals | |
| 3. Loose terminal connections | 3. Test internal diodes with multimeter diode mode | |
| Severe overheating | 1. Overloaded current | 1. Ensure load current does not exceed 40A (derate per cable specification) |
| 2. Poor heat dissipation | 2. Reserve sufficient clearance for heat dissipation (50mm top & 맨 아래) | |
| 3. 지나치게 높은 주변 온도 | 3. Lower ambient temperature or add ventilation | |
| Failed parallel operation of power supplies | 1. Reverse wiring polarity | 1. Recheck wiring polarity |
| 2. Excessive voltage difference between two inputs | 2. Keep voltage difference between two power supplies within 1V | |
| 3. Open-circuit internal diode | 3. Replace the faulty module | |
| Malfunction of reverse current protection | 1. Damaged reverse polarity protection diode | 1. Limit input voltage below 30VDC |
| 2. Input voltage over 60V | 2. Replace internal protection diode | |

6.2 On-site Quick Diagnosis Procedure
- 육안검사
Check housing for burn marks, deformation or discoloration.
Inspect terminals for looseness, oxidation and corrosion.
Remove dust accumulated on heat sinks which impairs heat dissipation.
- Electrical Testing
Measure input voltage to confirm it is within 0~30VDC.
Measure output voltage (normally input voltage minus 0.5V).
Test diode forward/reverse resistance: normal state is forward conduction and reverse cut-off.
- Function Verification
Disconnect one power supply and confirm the other works normally.
Restore dual power input and check uniform load distribution.
Measure temperature rise: shall not exceed ambient temperature +30°C.
