4. Configuració i instal·lació

4.1 Desembalatge

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

4.2 Muntatge

Mount the power supply in a stable location that allows for adequate airflow. Ensure there is sufficient space (at least 10-15 cm) around the unit for proper heat dissipation through free air convection. Avoid mounting near heat sources or in enclosed spaces without ventilation.

4.3 Vol d'entrada de CAtage Selecció

The LRS-200-12 features a selector switch for the AC input voltage gamma. Before connecting any power, ensure this switch is set to the correct voltage for your local power grid.

• Estableix a '90-132 VAC' for 110V/120V AC mains.
• Estableix a '180-264 VAC' for 220V/230V/240V AC mains.

Warning: Operating the unit with an incorrect input voltage selection can cause irreversible damage.

4.4 Connexions de cablejat

Connect the input and output wires to the terminal block as indicated on the unit. Use appropriate wire gauges for the expected current.

• AC Input Terminals:
  • L: Live/Phase
  • N: Neutre
  • F G: Frame Ground (Earth) - Crucial for safety.
• Terminals de sortida de CC:
  • +V: Positive DC Output (12V)
  • -V: Negative DC Output (Ground)

Assegureu-vos que totes les connexions estiguin ben fixades i degudament aïllades per evitar curtcircuits.

5. Funcionament

5.1 Encès

After all connections are made and verified, apply AC power to the unit. The power supply should turn on, and the output indicator (if present) will illuminate. Measure the output voltage to confirm it is within the expected range.

5.2 Vol. de sortidatage Ajust

The LRS-200-12 features a potentiometer (V.ADJ) for fine-tuning the output voltage. Using a small screwdriver, you can adjust the output voltage slightly above or below the nominal 12V. Always monitor the output voltage with a multimeter during adjustment to avoid over-voltage to your connected load.

6. Manteniment

The MEAN WELL LRS-200-12 is designed for reliable operation with minimal maintenance. However, periodic checks can help ensure its longevity.

• Neteja: Periodically clean the exterior of the unit to prevent dust accumulation, especially around ventilation areas. Use a soft, dry cloth. Do not use liquid cleaners.
• Inspecció: Regularly inspect wiring connections for tightness and signs of wear or corrosion. Check for any unusual noises or odors during operation.
• Ventilació: Ensure that the installation environment continues to provide adequate free air convection. Clear any obstructions that may impede airflow.

Note: There are no user-serviceable parts inside the power supply. Refer all servicing to qualified service personnel.
