5. Configuración e instalación

The NDR120-24 power supply is designed for easy DIN rail mounting. Follow these steps for proper installation:

  1. Montaxe:
    • Ensure the DIN rail is securely fastened within the enclosure or distribution box.
    • Align the power supply's DIN rail clip with the top edge of the DIN rail.
    • Press the bottom of the power supply firmly against the DIN rail until it clicks into place. Verify it is securely attached and does not wobble.
  2. Wiring (Input):
    • Before wiring, ensure the main power supply is OFF.
    • Connect the AC input wires to the "N" (Neutral) and "L" (Line) terminals.
    • Connect the ground wire to the "PE" (Protective Earth) terminal.
    • Ensure all connections are tight. The recommended terminal torque is 9 Lb-in.
  3. Wiring (Output):
    • Connect the positive (+) load wire to the "+V" output terminal.
    • Connect the negative (-) load wire to the "-V" output terminal.
    • If using multiple output terminals, ensure proper load balancing if applicable.
    • Ensure all connections are tight. The recommended terminal torque is 9 Lb-in.
  4. Ventilación: Ensure adequate clearance around the power supply for proper airflow and heat dissipation. Do not obstruct ventilation holes.

6. Instrucións de funcionamento

Once the power supply is securely installed and wired, follow these steps for operation:

  1. Encendido: Turn on the main AC power supply to the unit. The "DC OK" indicator light on the front panel should illuminate, indicating stable DC output.
  2. Vol. De saídatage Axuste:
    • The power supply features a "+V ADJ" potentiometer for fine-tuning the output voltage.
    • Using a small flat-head screwdriver, carefully turn the potentiometer clockwise to increase the voltage ou en sentido antihorario para diminuílo.
    • Monitorizar o volume de saídatage with a multimeter to ensure it is within the desired range for your application. Do not exceed the maximum specified voltage.
  3. Conexión de carga: Connect your 24VDC devices to the output terminals. Ensure the total current draw does not exceed 5A.
  4. Seguimento: Periodically check the "DC OK" indicator and the performance of connected devices to ensure stable operation.

7. Mantemento

The NDR120-24 power supply is designed for reliable operation with minimal maintenance. However, regular checks can help ensure longevity and optimal performance:

  • Limpeza: Periodically clean the exterior of the power supply to prevent dust accumulation, especially around ventilation openings. Use a soft, dry cloth. Do not use liquid cleaners or solvents.
  • Comprobacións de conexión: Annually, or as needed, verify that all input and output terminal connections remain tight and secure. Loose connections can lead to overheating or intermittent operation.
  • Condicións ambientais: Ensure the operating environment remains within the specified temperature and humidity ranges. Avoid exposure to excessive moisture, dust, or corrosive substances.
