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

[Volt Amp Adjustment]
Input voltage: 110V or 220V.
Adjustable output voltage range: DC 0-24V, with 0.1V precision. Suitable for 5V devices, 9V devices, 12V devices, and 24V devices.
Maximum current: 20A. The output current can be adjusted with the potentiometer. Regardless of the voltage adjustment, the maximum current should not exceed 20A. Suitable for devices rated at 2A, 3A, 5A, 10A, 12A, 15A, or 20A; use with devices below 20A. [Hardware] This buck converter is equipped with an LED screen, heat sink, and cooling fan. The LED screen clearly displays output voltage and output current. The heat sink and cooling fan help keep the temperature within a safe range. The cooling fan automatically activates during high-power operation with low noise. [Easy Operation] No installation is needed. Connect the wires and adjust the output as needed. The potentiometer is recessed into the power supply and can be rotated to adjust output parameters. [Protection] Overload protection, overvoltage protection, and short-circuit protection help protect connected devices from damage. The default input voltage is 220V; switch the input voltage to 110V or 220V according to local voltage. [Wide Application] This power supply can be used as a 5V, 12V, or 24V power supply for RV, Car, Laptop, Labtop, Computer, Lab, and CCTV applications
