48V Power Supply, AC 110V/220V to DC 0-48V 0-10A 480W Buck Converter, Volt Amp Adjustable Adapter Regulated 5V 12V 24V 30V 36V 48V Volt Switching Voltage LED Transformer Charger for Computer

Input voltage can be set to 110V or 220V. Wide adjustable output voltage range: DC 0-48V. This power supply is suitable for 5V, 9V, 12V, 24V, 30V, 36V, and 48V devices. Voltage precision is 0.1V. Note: The maximum current is 10A. The output current can be adjusted via the potentiometer. Regardless of the adjusted voltage, the maximum current must not exceed 10A. It can be used with devices rated for 2A, 3A, 5A, or 10A. Ensure connected devices are rated below 10A. This buck converter comes with an LED screen, heat sink, and cooling fan. The LED screen clearly shows the output voltage and current. The heat sink and cooling fan help maintain the temperature within a safe range. When operating at high power, the cooling fan turns on automatically with minimal noise. No installation is needed. After wiring, it can be used to adjust the output conveniently. The potentiometer is inset into the unit. Simply turn the potentiometer to adjust the output parameters. Features Overload Protection, Overvoltage Protection, and Short Circuit Protection to help protect connected devices. Note: The default input voltage is set to 220V. Before use, please switch the input voltage to 110V or 220V according to your local mains voltage. This power supply has versatile applications. It can serve as a 5V, 12V, 24V, 30V, 36V, or 48V power supply for RVs, cars, laptops, computers, labs, CCTV systems, and more
