5. 설치
Proper installation is crucial for the safe and reliable operation of the power supply.
5.1 장착
- 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 배선
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. 운영
Once installed and wired correctly, the HDR-150-48 is ready for operation.
- Before applying power, double-check all wiring connections for correctness and security.
- 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.
- 출력 볼륨tage 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. 유지관리
The HDR-150-48 power supply is designed for reliable, long-term operation with minimal maintenance.
- 청소: 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.
