1. АЦ улаз: Connect your AC mains power to the terminals labeled 'L' (Live), 'N' (Neutral), and '⊗' (Ground). Ensure secure connections.
2. ДЦ излаз: 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. Волtagе Подешавање: 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. Упутство за употребу

1. Прво појачање: After all connections are secure and the input voltage switch is correctly set, apply AC power to the unit.
2. ЛЕД индикатор: A green LED indicator (if present) will illuminate, signifying that the power supply is operational.
3. Учитавање везе: Connect your 12V DC load to the output terminals. Ensure the total current draw does not exceed 29A.
4. Вентилатор за хлађење: 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. Одржавање

• Чишћење: 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.
• Провере везе: Regularly inspect all wiring connections to ensure they are tight and secure. Loose connections can lead to poor performance or safety hazards.
• Услови животне средине: Ensure the operating environment remains within the specified temperature and humidity ranges to prolong the lifespan of the unit.
