5. Configuració i instal·lació

5.1 Vol d'entradatage Selecció

The power supply has a switch to select the AC input voltage. For North American regions, ensure the switch is set to 110V. Verify this setting before connecting the power supply to the mains.

5.2 Instruccions de cablejat

Follow the wiring diagram carefully. Incorrect wiring can cause damage to the unit or connected devices, and poses a safety risk.

Wiring instructions for the power supply, showing AC input terminals (L, N, Earth) and DC output terminals (V+, V-).

Figure 5.1: Detailed wiring instructions for AC input and DC output.

Entrada de CA: Connect the Live wire to 'L', Neutral wire to 'N', and Earth wire to the ground symbol terminal.
Sortida de corrent continu: Connect the positive load wire(s) to 'V+' terminals and the negative load wire(s) to 'V-' terminals. Multiple V+ and V- terminals are provided for convenience and current distribution.

5.3 Vol. de sortidatage Ajust

The power supply features a RHEOSTAT (potentiometer) for fine-tuning the DC output voltage. This allows for an adjustment range of approximately ±5% around the nominal 48V output. Use a small screwdriver to carefully turn the adjustment screw. Monitor the output voltage with a multimeter during adjustment to avoid over-voltage to your connected devices.

6. Instruccions de funcionament

After completing all wiring and verifying connections, connect the power supply to the AC mains.
An operation LED indicator will illuminate, confirming the unit is powered on.
Ensure the total current draw of your connected devices does not exceed 25 Amps.
The integrated fan cooling system will activate as needed to maintain optimal operating temperature.

9. Solució De Problemes

Sense potència de sortida:
- Comproveu si el vol d'entrada de CAtage switch is correctly set (110V).
- Verify that the AC input power cable is securely connected and the power source is active.
- Comproveu si hi ha interruptors automàtics saltats o fusibles fundits al circuit d'alimentació.
- Ensure the operation LED is illuminated. If not, the unit may not be receiving power or may be faulty.
Low or Unstable Output Voltage:
- Check the load connected to the power supply. An overload can cause voltage gota.
- Ajusteu el volum de sortidatage using the RHEOSTAT (potentiometer) as described in Section 5.3.
- Ensure all DC output connections are secure.
Sobreescalfament:
- Ensure adequate ventilation around the unit. Clear any obstructions from the fan and vents.
- Reduce the load if it exceeds the power supply's capacity.
Unit Shuts Down:
- This may indicate activation of over-load, over-voltage, or short-circuit protection.
- Disconnect the load, power cycle the unit, and reconnect the load gradually to identify the issue.
- Check for short circuits in the connected load wiring.
