Setup
Follow these steps to properly set up your ALITOVE power supply:
- Verify Device Compatibility: Before connecting, confirm that your electronic device requires 12V DC power and its current draw is 3A or less.
- Check DC Connector Size and Polarity: The power supply's DC plug has an outer diameter of 5.5mm and an inner core diameter of 2.1mm or 2.5mm. Ensure your device's power input port matches these dimensions. The inner core polarity is positive (+), and the outer barrel polarity is negative (-).
- Connect to Device: Plug the DC output connector of the power supply into your device's power input port. If using the included quick wiring connector, screw the wires from your device into the connector terminals, ensuring correct polarity.
- Connect to Power Outlet: Plug the AC input plug of the power supply into a standard 100-240V AC wall outlet.

Operating Instructions
Once the power supply is correctly connected to your device and a power outlet, it will automatically begin providing power. A small blue LED indicator on the adapter will illuminate to confirm that power is being supplied.
For optimal performance and longevity, it is recommended that the maximum load on the power supply does not exceed 80% of its full capacity. For this 12V 3A (36W) power supply, devices requiring up to 29W are ideal.

Maintenance
To ensure the longevity and proper functioning of your ALITOVE power supply, follow these maintenance guidelines:
- Cleaning: Regularly wipe the exterior of the power supply with a dry, soft cloth to remove dust and dirt. Do not use liquid cleaners or solvents.
- Storage: Store the power supply in a cool, dry place away from direct sunlight and extreme temperatures when not in use.
- Cable Care: Avoid bending or crimping the power cord excessively. Do not place heavy objects on the cable.
- Inspection: Periodically inspect the power supply and cables for any signs of damage, such as frayed wires or cracked casing. Discontinue use if damage is found.
Troubleshooting
If you encounter issues with your power supply, refer to the following common problems and solutions:
- Device Not Powering On:
- Ensure the power supply is securely plugged into a working AC outlet.
- Verify that the DC connector is firmly seated in your device's power input port.
- Confirm that your device's voltage and current requirements match the power supply's specifications (12V DC, 3A max).
- Check if the power supply's LED indicator is illuminated. If not, try a different outlet.
- Power Supply Overheating:
- Ensure adequate ventilation around the power supply. Do not cover it or place it in an enclosed space.
- Verify that the connected device's current draw does not exceed 3A. Overloading can cause overheating.
- Intermittent Power:
- Check all connections for looseness.
- Inspect the power cord and connectors for any visible damage.
If the problem persists after attempting these solutions, please contact ALITOVE customer support.
