5. Installation
Proper installation is crucial for the safe and reliable operation of the power supply.
5.1 Montage
- Ensure the mounting surface is stable and capable of supporting the weight of the power supply.
- Mount the HDR-150-48 onto a standard TS-35/7.5 or TS-35/15 DIN rail.
- Allow adequate clearance around the unit for proper ventilation (minimum 10-15mm on all sides). Do not block ventilation holes.
- Mount the unit vertically to optimize heat dissipation.
5.2 Câblage
CAUTION: Disconnect all power before wiring. Incorrect wiring can damage the unit and pose a safety hazard.
- Identify the input terminals (AC L, AC N, FG) and output terminals (V+, V-). Refer to Figure 3 for terminal locations.
- Connect the AC input wires (Live and Neutral) to the respective AC L and AC N terminals.
- Connect the Earth Ground wire to the FG (Frame Ground) terminal. This connection is essential for safety.
- Connect the load to the output terminals: positive (+) to V+ and negative (-) to V-. Ensure correct polarity.
- Use appropriate wire gauges for the expected current draw to prevent overheating.
- Tighten all terminal screws securely to prevent loose connections.

6. Fonctionnement
Once installed and wired correctly, the HDR-150-48 is ready for operation.
- Avant de mettre l'appareil sous tension, vérifiez minutieusement que tous les branchements électriques sont corrects et sécurisés.
- Apply AC input power to the unit.
- The LED indicator on the front panel (refer to Figure 1) should illuminate, indicating that the power supply is operating.
- Le volume de sortietage is factory set to 48V. Some models may have a voltage adjustment potentiometer; if present, use a non-conductive tool to make minor adjustments within the specified range.
- Ensure the total load connected to the output does not exceed the rated output power of 154W or the rated current of 3A.
7. Entretien
The HDR-150-48 power supply is designed for reliable, long-term operation with minimal maintenance.
- Nettoyage: Periodically inspect the unit for dust accumulation, especially around ventilation openings. Disconnect power and use a soft, dry brush or compressed air to gently clean the exterior. Do not use liquid cleaners.

8. Dépannage
If the power supply is not functioning as expected, consider the following common issues and solutions:
| Problème | Cause possible | Solution |
|---|---|---|
| No output, LED off | No input power; Incorrect wiring; Internal fault | Check AC input power source and connections. Verify wiring. If problem persists, unit may be faulty. |
| Volume de sortietage too low or fluctuating | Overload; Short circuit; Input voltage trop bas | Reduce load. Check for short circuits in the output wiring. Verify input voltage est dans la plage. |
| Unit is hot, shuts down intermittently | Overload; Insufficient ventilation; Over-temperature protection activated | Reduce load. Ensure adequate airflow around the unit. Check ambient temperature. |
| LED is on, but no output | Output wiring issue; Load fault; Internal fault | Check output wiring for breaks or loose connections. Test the load independently. |
If troubleshooting steps do not resolve the issue, contact qualified service personnel or the manufacturer for assistance. Do not attempt to repair the unit yourself.
