4. Configurazione e installazione

Per una corretta installazione dell'alimentatore LRS-350-12, seguire questi passaggi.

4.1 Disimballaggio

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 Ingresso Voltage Selezione

Before connecting any power, ensure the AC input voltagL'interruttore di selezione è impostato sul voltage for your region (115VAC for North America, 230VAC for most other regions). This switch is typically located on the side of the unit.

1. Ingresso CA: Connect your AC mains power to the terminals labeled 'L' (Live), 'N' (Neutral), and '⊗' (Ground). Ensure secure connections.
2. Uscita CC: 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. Voltage Regolazione: 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. Istruzioni per l'uso

1. Accensione iniziale: Dopo che tutte le connessioni sono sicure e il volume di ingressotage switch is correctly set, apply AC power to the unit.
2. Indicatore LED: A green LED indicator (if present) will illuminate, signifying that the power supply is operational.
3. Connessione di carico: Connect your 12V DC load to the output terminals. Ensure the total current draw does not exceed 29A.
4. Ventola di raffreddamento: 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. Manutenzione

• Pulizia: 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.
• Verifiche della connessione: Regularly inspect all wiring connections to ensure they are tight and secure. Loose connections can lead to poor performance or safety hazards.
• Condizioni ambientali: Ensure the operating environment remains within the specified temperature and humidity ranges to prolong the lifespan of the unit.
