2. Informazioni sulla sicurezza
- Nota importante: This product is an AC to DC adapter, NOT a charger. It is not intended for charging electronic devices with batteries, such as laptops.
- Always confirm the correct voltage, current, power port type, and polarity required by your device before connecting the power supply. Using an incorrect voltage or polarity can cause irreversible damage to your device.
- It is recommended to operate the power supply at less than 80% of its full load capacity (i.e., less than 4A for 12V output) to ensure optimal performance and extend its service life. Overloading can lead to overheating and reduced lifespan.
- The power supply incorporates multiple safety protection systems: automatic over-voltage cut-off, over-current cut-off, over-temperature cut-off, and short-circuit cut-off.
- For indoor use only. Keep the device away from water, moisture, and high temperatures.
- Do not disassemble or attempt to repair the unit yourself. Refer to qualified service personnel for any repairs.

5. Istruzioni per l'installazione
- Identificare i requisiti del dispositivo: Before connecting, confirm your device's required voltage (V), current (A), power port size, and polarity (center positive or center negative). This information is usually found on the device itself, its original power adapter, or in its user manual.
- Select the Correct DC Tip: Choose the appropriate DC tip from the provided 14 options that matches your device's power port. If your device requires a specific polarity that differs from the default center positive of the power supply, use the included polarity converter cable.
- Connect the Tip: Firmly attach the selected DC tip to the power supply's output cable. If needed, connect the polarity converter cable between the power supply cable and the chosen DC tip.
- Collegare alla presa a muro: Insert the AC input plug of the power supply into a standard 100-240V AC wall outlet. The LCD display on the power supply will illuminate.
- Regola voltage: Ruota il voltage adjustment knob on the power supply until the LCD display shows the exact voltage richiesto dal tuo dispositivo. Do this before connecting to your device.
- Connetti al dispositivo: Una volta che il voltage is set, insert the DC tip into your device's power input port.

6. Istruzioni per l'uso
- Accensione/spegnimento: The power supply can be turned on or off by rotating the adjustment knob to the 'off' position. This eliminates the need to unplug the unit from the wall for simple power cycling.
- Voltage Regolazione: Per modificare il volume di uscitatage, rotate the knob clockwise to increase the voltage and counter-clockwise to decrease it. The LCD display will update in real-time. Always adjust the voltage to the desired level Prima connecting it to your electronic device.
- Sostituzione della punta: To replace a DC tip, simply pull the current tip off the power supply cable and push the new tip firmly into place. Ensure a secure connection.
- Polarity Conversion: If your device requires center negative polarity, connect the polarity converter cable between the power supply's output cable and the chosen DC tip. This will reverse the polarity from center positive to center negative.
