5. Instrucións de configuración

Follow these steps to set up your Wefomey Universal Power Supply:

Determine Device Voltage: Identify the required input voltage and current for your electronic device. This information is usually found on the device itself, its original power adapter, or in its user manual.
Select DC Tip: Choose the appropriate DC connector tip from the 14 included tips that matches your device's power input port. Ensure a snug fit.
Comprobar polaridade: Most devices use a center-positive polarity (inner positive, outer negative). The Wefomey power supply's default output is center-positive. If your device requires center-negative polarity, use the included reverse polarity converter cable. Connect the converter cable between the selected DC tip and the power supply's output cable.
Set Voltage: Plug the power supply into a standard AC outlet (100-240V). The LCD display will illuminate. Rotate the voltage adjustment dial to set the desired output voltage. Carefully adjust until the LCD displays the exact voltage requirido polo seu dispositivo.
Conectar ao dispositivo: Unha vez que o voltage is correctly set and the tip/polarity are confirmed, connect the power supply to your electronic device.

6. Instrucións de funcionamento

Once set up, operating the power supply is straightforward:

Encendido/apagado: The power supply activates when plugged into an AC outlet and deactivates when unplugged.
Voltage Axuste: Use the rotary dial labeled 'VOLTAGE' to fine-tune the output voltage. The LCD display provides real-time feedback on the selected voltage.
Usando pinzas de cocodrilo: For devices without a standard DC input, attach the alligator clip test lead to the power supply's output. Ensure correct polarity (red for positive, black for negative) when connecting to your device's terminals.
Monitoring Load: While the power supply has safety features, it is good practice to monitor your device's performance. If the power supply feels excessively hot or the device behaves erratically, disconnect immediately.
