Wefomey 120W Universal Power Supply Adjustable DC 3V-24V User Manual

Введение

This manual provides essential instructions for the safe and efficient use of your Wefomey 120W Universal Power Supply. Please read this manual thoroughly before operation and retain it for future reference. This device is designed to provide adjustable DC power for a wide range of compatible electronic devices.

Меры предосторожности

To ensure safe operation and prevent damage to the unit or connected devices, please observe the following:

• Томtagд Выбор: Always select the correct output voltage (3V to 24V) using the adjustment knob до connecting the power supply to your device. Incorrect voltage can cause irreversible damage to your equipment.
• Грузоподъемность: It is recommended to use the power supply at less than 80% of its maximum load capacity (120W / 5A) to ensure optimal performance and longevity.
• Polarity Converter: The included polarity converter cable reverses the output polarity. Only use this cable if your device explicitly requires center-negative polarity. Misuse can severely damage your electronic device. It is not an extension cord.
• Только для использования в помещении: Данный блок питания предназначен для использования в помещении в сухих условиях. Не допускайте попадания воды, влаги или высокой влажности.
• Функции защиты: The unit includes built-in safety systems for automatic over voltage cut-off, over current cut-off, over temperature cut-off, and short circuit cut-off. These features help protect the power supply and connected devices.
• Вентиляция: Ensure adequate ventilation around the power supply during operation to prevent overheating.
• Обслуживание: Do not attempt to open, modify, or repair the power supply. Refer all servicing to qualified personnel.

Инструкции по установке

Follow these steps to set up your universal power supply:

1. Подключите вход переменного тока: Plug the AC input cable into a standard 100-240V AC wall outlet.
2. Select DC Tip: Identify the correct DC tip that matches the power input port of your device. Connect this tip securely to the power supply's DC output cable.
3. Установить выходную громкостьtage: Before connecting to your device, rotate the voltage adjustment knob on the power supply to set the required output voltage. The digital LCD display will show the current voltage. Adjust carefully as the knob can be sensitive.
4. Check Polarity (if necessary): Most devices use a center-positive polarity. If your device requires center-negative polarity, attach the included reverse polarity converter cable between the DC output cable and the selected DC tip. Refer to your device's manual for its specific polarity requirements.
5. Подключиться к устройству: Как только объемtage and polarity are correctly set, connect the DC output cable (with the appropriate tip and polarity converter, if used) to your electronic device.

Инструкция по эксплуатации

After successful setup, the power supply will deliver power to your connected device at the selected voltage.

• Изменение объемаtage: Чтобы отрегулировать громкостьtage for a different device or requirement, first disconnect the power supply from your device. Then, adjust the voltage knob to the new desired setting, and finally, reconnect to your device.
• Мониторинг: The LCD display provides real-time feedback on the output voltage. Periodically check this display to ensure the voltage remains stable and correct for your application.

Understanding the Polarity Converter

The included polarity converter cable is designed to reverse the output polarity of the DC tip. Most electronic devices use a center-positive polarity (inner positive, outer negative). The converter changes this to center-negative (inner negative, outer positive).

ПРЕДУПРЕЖДЕНИЕ: Only use the polarity converter if your device explicitly requires center-negative polarity. Using it incorrectly can cause severe and irreparable damage to your electronic device. This cable is not an extension cord and should only be used for polarity reversal.

Поиск неисправностей

If you encounter issues with your Wefomey Universal Power Supply, refer to the following common solutions:

Нет выходной мощности

• Ensure the AC input cable is securely plugged into both the power supply and a functioning wall outlet.
• Убедитесь, что выходной объемtage is set above 0V on the adjustment knob.

Device Not Functioning

• Томtage: Double-check that the correct voltage is selected on the power supply, matching your device's requirements.
• DC Tip: Confirm that the correct DC tip is used and securely connected to your device.
• Полярность: Ensure the polarity (center-positive or center-negative) matches your device's specifications. If necessary, use the polarity converter cable correctly.
• Требования к питанию: Verify that your device's power requirement (Amps/Watts) does not exceed the power supply's maximum output (5A / 120W).

Томtagе Дрифт

• Some slight voltage drift (approximately 0.1V to 0.2V) may occur during prolonged use or under varying loads. This is generally within acceptable operating limits for most devices.
