4. Орнотуу жана орнотуу

LRS-350-12 электр менен жабдууну туура орнотуу үчүн бул кадамдарды аткарыңыз.

4.1 Пакеттен чыгаруу

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 Input Voltage Тандоо

Before connecting any power, ensure the AC input voltage тандоо которгучу туура томго коюлганtage 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 киргизүү: Connect your AC mains power to the terminals labeled 'L' (Live), 'N' (Neutral), and '⊗' (Ground). Ensure secure connections.
2. DC чыгаруу: 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. Тtage Тууралоо: 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. Иштөө нускамалары

1. Баштапкы кубаттоо: After all connections are secure and the input voltage switch is correctly set, apply AC power to the unit.
2. Индикатор LED: A green LED indicator (if present) will illuminate, signifying that the power supply is operational.
3. Туташуу жүктөө: Connect your 12V DC load to the output terminals. Ensure the total current draw does not exceed 29A.
4. Муздатуу желдеткич: 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. Техникалык тейлөө

• Тазалоо: 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.
• Туташуу текшерүүлөрү: Regularly inspect all wiring connections to ensure they are tight and secure. Loose connections can lead to poor performance or safety hazards.
• Экологиялык шарттар: Ensure the operating environment remains within the specified temperature and humidity ranges to prolong the lifespan of the unit.
