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

[Volt Adjustment] Input voltage can be 110V or 220V.
Wide adjustable output voltage range: DC 0-24V. This supply is suitable for 5V 9V 12V 24V devices. The voltage precision is 0.1V.
Note: The maximum current is 20A. But the actual current depends on the load. No matter how the voltage is adjusted, the current is 20A and cannot be regulated. It can be used with devices of 2A 3A 5A 10A 12A 15A 20A. Make sure to use devices that are below 20A. [Hardware] This Buck Converter is equipped with an LED screen, heat sink and cooling fan. The LED screen can clearly display the output voltage. The heat sink and cooling fan can control the temperature within a safe range. When running power is high, the cooling fan will automatically activate with little noise. [Easy Operation] This supply requires no installation; after connecting the wire, it can be used to adjust output, which is convenient. The potentiometer is inset into the supply. Rotating the potentiometer adjusts the output parameter. [Protection] Over Load Protection, Over Voltage Protection, Short Circuit Protection, which can protect your device from damage.
Note: The default input voltage is 220V. Before using, please switch the input voltage to 110V/220V according to your city voltage. [Wide Application] This power supply has variable application. It can be used as a 5V 12V 24V power supply for RV, Car, Laptop, Computer, Lab, CCTV, etc
