24V Power Supply, AC 110V/220V to DC 0-24V 0-20A 480W Buck Converter, Volt Amp Adjustable Adapter Regulated 5V 12V 24V Volt Switching Voltage LED Transformer Charger for Computer CCTV Lab

**Voltage and Current Adjustment** The input voltage can be set to 110V or 220V. It offers a wide adjustable output voltage range of DC 0-24V. This power supply is suitable for 5V, 9V, 12V, and 24V devices. Voltage precision is 0.1V. Note: The maximum current is 20A. The output current can be adjusted via the potentiometer. Regardless of the set voltage, the maximum current must not exceed 20A. It can be used with devices rated for 2A, 3A, 5A, 10A, 12A, 15A, or 20A. Ensure the connected device operates below 20A. **Hardware** This buck converter comes with an LED screen, a heat sink, and a cooling fan. The LED screen clearly shows the output voltage and output current. The heat sink and cooling fan help keep the operating temperature within a safe range. During high-power operation, the cooling fan turns on automatically with very little noise. **Easy Operation** No installation is needed. After wiring, it can be used to adjust the output conveniently. The potentiometer is built into the unit. Simply turn the potentiometer to adjust the output parameters. **Protection** It features Overload Protection, Overvoltage Protection, and Short Circuit Protection to help protect connected equipment. Note: The default input voltage setting is 220V. Before use, please switch the input voltage to 110V or 220V according to your local mains voltage. **Wide Application** This variable power supply has versatile uses. It can serve as a 5V, 12V, or 24V power supply for RVs, cars, laptops, computers, labs, CCTV systems, and other applications
