5. Instrucións de configuración
- Identificar os requisitos do dispositivo: Determine the exact voltage (V), current (A), and polarity (center positive or center negative) required by your electronic device. This information is usually found on the device itself, its original power adapter, or in its user manual.
- Select the Correct DC Tip: Choose one of the 14 provided DC tips that physically fits your device's power input port.
- Comprobar polaridade: Most devices use center-positive polarity. If your device requires center-negative polarity, attach the included reverse polarity converter to the selected DC tip. Ensure the polarity matches your device's requirements.
- Connect DC Tip to Adapter: Firmly insert the selected DC tip (with or without polarity converter) into the output cable of the Wefomey power supply.
- Establecer Vol. Saídatage: Before connecting to your device, plug the power supply into an AC outlet. Turn the voltage adjustment knob to set the desired output voltage, as indicated on the LCD display. Double-check that the voltage matches your device's requirement.
- Conectar ao dispositivo: Unha vez que o voltage is correctly set, connect the DC tip to your electronic device's power input port.
