Package Contents
The package includes:
- 1 x ALITOVE DC 12V 20A 240W Power Supply
Note: A power cord is not included and must be purchased separately.
Setup and Installation
1. Input Voltage Selection
Before connecting any power, locate the red switch on the side of the unit. This switch allows you to select between 110V and 220V AC input. Ensure this switch is set to the correct voltage for your region to prevent damage to the power supply and connected devices.

2. Wiring Connections
Refer to the terminal block on the power supply for wiring. Always ensure the power supply is disconnected from the AC mains before making any connections.
- AC Input: Connect your AC power cord to the L (Live) and N (Neutral) terminals.
- Ground: Connect the earth ground wire to the GND terminal.
- DC Output: Connect your DC devices to the +V (positive) and COM (negative) terminals. There are three sets of output terminals for convenience.

3. Output Voltage Adjustment
The DC 12V output voltage can be adjusted by approximately 15%. Use a small screwdriver to carefully turn the "V ADJ" potentiometer located near the output terminals. Turn clockwise to increase voltage, counter-clockwise to decrease. Monitor the output voltage with a multimeter during adjustment.

Operating Instructions
- After completing all wiring connections and verifying the input voltage switch setting, connect the power supply to the AC mains.
- The indicator light on the terminal block will illuminate, indicating the unit is powered on and providing DC output.
- Ensure the total current draw of all connected devices does not exceed 20A and the total power does not exceed 240W.
- The power supply is designed for continuous operation within its specified limits.

Maintenance
- Cleaning: Disconnect the power supply from the AC mains before cleaning. Use a dry, soft cloth to wipe the exterior. Do not use liquid cleaners or solvents.
- Ventilation: Periodically check that the ventilation holes are not obstructed by dust or debris. Clean as necessary to maintain efficient heat dissipation.
- Inspection: Regularly inspect the wiring connections for any signs of wear, corrosion, or loose connections.
- Storage: Store the power supply in a cool, dry place when not in use.
