4. Especificacions

5. Contingut del paquet

El paquet normalment inclou:

• 1 x LETOUR 12V 30A 360W Switching Power Supply Unit

Note: Additional accessories such as power cords or connectors may be sold separately.

6. Configuració i instal·lació

Before proceeding with installation, ensure the power supply is disconnected from any AC power source.

6.1 Muntatge

The power supply is designed for surface mounting. Choose a stable, dry, and well-ventilated location. Ensure there is adequate space around the unit for airflow, especially around the fan and ventilation grilles.

6.2 Instruccions de cablejat

Refer to the diagram below and the labels on the power supply for correct wiring. Incorrect wiring can cause damage or pose a safety hazard.

1. AC Input (Mains):
   • Connecteu el Fire line (Live) to the terminal marked 'L'.
   • Connecteu el Zero line (Neutral) to the terminal marked 'N'.
   • Connecteu el Cable de terra to the terminal marked 'E' (chassis ground). This is crucial for safety.
2. Sortida de corrent continu:
   • Connecteu el Sortida positiva of your device to the terminal marked '+V'.
   • Connecteu el Negative Electrode of your device to the terminal marked '-V'.

6.3 Vol d'entradatage Selecció

This power supply supports a wide AC input range. Ensure the input voltagl'interruptor (si n'hi ha i és accessible) està ajustat al volum correctetage for your region (e.g., 110V or 220V). Refer to the product label for specific instructions.

6.4 Vol. de sortidatage Ajust

El voltage can be finely adjusted by approximately ±10% using the potentiometer labeled 'ADJ'. Use a small screwdriver to carefully turn the potentiometer clockwise to increase voltage or counter-clockwise to decrease it. It is recommended to adjust the voltage while monitoring with a multimeter to ensure the desired output.

7. Instruccions de funcionament

Once properly installed and wired, connect the power supply to an appropriate AC power source. The power supply will convert the AC input to a stable 12V DC output. Ensure that the total current draw of your connected devices does not exceed the power supply's maximum output of 30A (360W) to prevent overload and potential damage.

8. Manteniment

Un manteniment regular ajuda a garantir la longevitat i el rendiment òptim de la vostra font d'alimentació.

• Neteja: Periodically clean the exterior of the power supply with a dry, soft cloth. Ensure ventilation openings are free from dust and debris. Do not use liquid cleaners.
• Inspecció del ventilador: The power supply includes an internal cooling fan. Ensure the fan is not obstructed and operates quietly. Excessive noise or fan failure may indicate a problem.
• Ventilació: Always ensure the power supply is in a well-ventilated area to prevent heat buildup.

9. Solució De Problemes

Si teniu problemes amb la font d'alimentació, consulteu els problemes i solucions més comuns següents:

• Sense potència de sortida:
  • Check all AC input and DC output connections for secure contact.
  • Comproveu que el vol d'entrada de CAtage is within the specified range (85-240V) and the input voltage switch (if applicable) is correctly set.
  • Ensure the power supply is receiving power from the wall outlet.
• Voltage Sag or Instability:
  • This often indicates an overload. Reduce the total load connected to the power supply. Ensure the total current draw does not exceed 30A.
  • Check for short circuits in the connected load.
• Excessive Noise (Fan or Electronic Whine):
  • A loud fan may indicate dust buildup or a failing fan bearing. Clean the fan and ventilation areas.
  • Electronic whine can sometimes occur under certain load conditions. If it's excessive or new, ensure the load is within specifications and consider contacting support.
• Sobreescalfament:
  • Ensure the power supply has adequate ventilation and is not covered.
  • Reduce the connected load if the unit is running continuously at near-maximum capacity.

If the problem persists after attempting these troubleshooting steps, contact customer support.
