Installazione è installazione
1. Input Voltage Selezzione
The S-400-24 power supply supports both 110V AC and 220V AC input. A voltage selector switch is located on the side of the unit. Ensure this switch is set to the correct voltage for your region before connecting to AC power. Vol. incorrettutage selection can cause severe damage to the unit and connected devices.

2. Muntà
Mount the power supply in a stable, well-ventilated area. Ensure there is adequate space around the unit for airflow, especially around the cooling fan and ventilation grilles. Use appropriate screws to secure the unit through its mounting tabs.
3. Wiring Connections
Refer to the terminal block for proper wiring. All connections should be made using appropriate gauge wires, securely fastened to prevent loose connections.
Figura 3: Fronte view of the power supply, detailing the screw terminal block for input and output connections.
Terminal Block Description:
- L, N: AC Power Input (Live and Neutral). Connect your main AC power source here.
- Terra: Earth Ground. Connect to a reliable earth ground for safety.
- -V (COM): DC Output Negative. Connect the negative terminal of your 24V DC load.
- +V: DC Output Positive. Connect the positive terminal of your 24V DC load.
- ADJ: Uscita Voltage Adjustment. Use a small screwdriver to fine-tune the output voltage within a small range (typically ±10%).
CAUTION: Double-check all wiring connections before applying power. Incorrect wiring can lead to damage, fire, or electric shock.
Istruzzioni di funziunamentu
- After completing all wiring and ensuring the input voltage selector is correct, connect the power supply to the AC mains.
- The LED indicator (if present) on the unit should illuminate, indicating power is on.
- Verificate l'output voltage using a multimeter at the +V and -V terminals before connecting your load. Adjust the ADJ potentiometer if necessary.
- Connect your 24V DC load to the +V and -V terminals.
- The power supply features built-in protections against overcurrent, overvoltage, and short circuits. In case of a fault, the unit may shut down automatically. Disconnect power, resolve the issue, and then reconnect power.
Mantenimentu
The PPOZYLPC S-400-24 is designed for reliable operation with minimal maintenance. Follow these guidelines:
- Pulizia: Periodically clean the exterior of the unit, especially the ventilation grilles, to prevent dust buildup. Use a soft, dry cloth. Do not use liquid cleaners.
- Ventilazione: Ensure that the cooling fan and ventilation openings remain unobstructed at all times. Poor ventilation can lead to overheating and reduced lifespan.
- Cunnessioni: Periodically check all wiring connections to ensure they remain tight and secure. Loose connections can cause intermittent operation or overheating.
