4. 설정 및 설치

LRS-350-12 전원 공급 장치를 올바르게 설치하려면 다음 단계를 따르십시오.

4.1 풀기

Carefully remove the power supply from its packaging. Inspect the unit for any physical damage. If damage is found, do not proceed with installation and contact your supplier.

4.2 입력 볼륨tage 선택

Before connecting any power, ensure the AC input voltage 선택 스위치가 올바른 볼륨으로 설정되어 있습니다.tage for your region (115VAC for North America, 230VAC for most other regions). This switch is typically located on the side of the unit.

1. AC 입력: Connect your AC mains power to the terminals labeled 'L' (Live), 'N' (Neutral), and '⊗' (Ground). Ensure secure connections.
2. DC 출력 : Connect your load to the terminals labeled '+V' (Positive 12V DC) and '-V' (Negative/Ground). Multiple '+V' and '-V' terminals are provided for convenience and to distribute current.
3. 권tag전자 조정: A small potentiometer (labeled 'V.ADJ' or similar) is available near the output terminals to fine-tune the output voltage within a small range. Use a small screwdriver to adjust if necessary.

5. 사용 설명서

1. 초기 전원 켜기: After all connections are secure and the input voltage switch is correctly set, apply AC power to the unit.
2. 표시 LED: A green LED indicator (if present) will illuminate, signifying that the power supply is operational.
3. 부하 연결: Connect your 12V DC load to the output terminals. Ensure the total current draw does not exceed 29A.
4. 냉각 팬: The built-in cooling fan operates automatically. It will turn on when the internal temperature (RTH3) reaches 50℃ and turn off when it drops below 40℃. This ensures optimal operating temperature.

6. 유지관리

• 청소: Periodically clean the exterior of the power supply with a dry, soft cloth. Ensure ventilation openings are free from dust and debris to maintain proper airflow for the cooling fan.
• 연결 확인: Regularly inspect all wiring connections to ensure they are tight and secure. Loose connections can lead to poor performance or safety hazards.
• 환경 조건: Ensure the operating environment remains within the specified temperature and humidity ranges to prolong the lifespan of the unit.
