2. Informações de segurança
To ensure safe operation and prevent damage to the power supply or connected devices, please observe the following safety guidelines:
- Somente para uso interno: This power supply is designed for indoor use. Do not expose it to water, moisture, or high humidity.
- Volumetage e Amperage Matching: Ensure your device requires 12V DC power and its current draw does not exceed 12A (144W). Connecting devices with higher power requirements will damage the adapter.
- Polaridade correta: Always verify the polarity of your device matches the adapter's output (internal positive "+", outside negative "-"). Incorrect polarity can cause severe damage.
- Evite sobrecarga: Do not connect devices that collectively draw more than 12A or 144W. It is recommended to operate at 80% or less of the maximum load (e.g., for a 144W adapter, power devices up to 115W).
- Ventilação: Ensure adequate ventilation around the power supply to prevent overheating. Do not cover the adapter during operation.
- Integridade do cabo: Regularly inspect the power cord for any signs of damage. Do not use if the cord is frayed or damaged.
- Desconecte quando não estiver em uso: Unplug the power supply from the wall outlet when not in use for extended periods.

4. Instruções de configuração
Follow these steps to set up your ALITOVE 12V DC Power Supply:
- Verifique a compatibilidade do dispositivo: Before connecting, confirm that your electronic device requires a 12V DC input and its power consumption (ampera/watttage) is within the 12A/144W limit of this adapter.
- Check DC Connector: Ensure your device's DC input port is compatible with the 5.5mm x 2.5mm or 5.5mm x 2.1mm barrel connector of the adapter.
- Confirm Polarity: Verify that your device's required polarity matches the adapter's (internal positive "+", outside negative "-").
- Connect DC Plug: Insert the DC output plug of the adapter firmly into your device's DC input port.
- Conecte o cabo de alimentação CA: Plug the AC power cord into the adapter's AC input socket.
- Conecte à tomada: Insert the AC power cord's plug into a standard 100-240V AC wall outlet.
- Ligar: The adapter typically has an indicator light that will illuminate when power is supplied. Your device should now receive power.
