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

This converter transforms standard wall AC mains (110 V or 220 V AC) into a variable DC output (any voltage between 0 V and 48 V), with up to 10 A output current (up to ~480 W total). It’s a regulated, adjustable power supply — useful when you need a stable DC supply for devices such as lab equipment, DC-powered tools, LED setups, CCTV cameras, small motors, battery charging or experiments.

Key Features

【Volt Adjustment】 Input Voltage can be 110V or 220V. Wide adjustable output Voltage range: DC 0-48V. This supply is suitable for 5V 9V 12V 24V 30V 36V 48V devices. The voltage precision is 0.1V. Note——The maximum current is 10A. But the actual current is depended on the load. No matter how many voltage is adjusted, the current is 10A and can not be regulated. It can be used to device of 2A 3A 5A 10A. Make sure to use the devices which is below 10A.
【Hareware】 This Buck Converter is equipped with LED screen, heat sink and cooling fan. The LED screen can clearly display the output voltage. Heat sink and cooling fan can control the temperature in a safe range. During the running power is high, the cooling fan will automatically activate with little noise.
【Easy Operation】 This supply is no need to install, after connecting wire, it can be used to adjust output, which is convenient. The potentiometer is inset into the supply. Only to rotate the potentiometer can adjust 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 switching 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 30V 36V 48V power supply for RV, Car, Labtop, Computer, Lab, CCTV, etc. All of our item has 1 year long time warranty guarantee.

Key Considerations

1

Output range & adjustment — 0 – 48 V DC adjustable, in 0.1 V precision steps.

2

Maximum current/power — up to 10 A (i.e. up to ~480 W) as long as load stays within limits.

3

Stability and regulation — The output is regulated (not a simple adapter), suitable for sensitive electronics needing stable DC voltage.

4

Thermal management — heat-sink + cooling fan, important if using near maximum load for extended periods.

5

Safety protections — over-voltage, over-current, short-circuit protections help safeguard both the converter and connected devices.

1

Because the converter allows you to set output anywhere from 0 V to 48 V, it's quite flexible. This makes it suitable for a variety of applications: from powering 5 V/12 V LEDs or small electronics, to 24 V motors, to 48 V devices — depending on your gear.

These factors represent the most critical aspects that will impact your satisfaction with this product.

Customer Reviews

Taig Micro lathe DC motor setup
2025-12-01T21:27:32.208Z

I am using this Drok 115VAC to 24V 20A variable power supply, along with a YaeTek 24V DC 350W Permanent Magnet Electric Motor, to drive my Taig Micro II lathe. Considering this whole kit cost about $80 I'm very happy with the result. While not perfect, the value is so high I have to give it 5 stars.

Pretty reliable unit, Well packaged, Good quality power supply, Current output is not adjustable.

I bought 2 of these units about 4 years ago, and they're still in daily use 7x24. --I thought I'd use as a general bench / lab power supply, however I didn't realize current out was not adjustable -(as the product description _clearly_ states!)

Frequently Asked Questions

Final Verdict

The DROK 110 V/220 V Converter Adjustable Transformer (B08GFQZFC1) is a versatile regulated DC power supply — ideal for projects, lab work, DIY electronics, battery charging, LED setups, small DC motors, CCTV or any equipment requiring adjustable stable DC voltage up to 48 V.However — it’s not a “AC-to-AC” converter (it doesn’t output 110 V or 220 V AC) — so you can’t use it to run typical household or AC-powered devices directly. If your goal is to power AC-appliances inside a car or from mains, you’ll need a proper inverter/step-down or step-up AC transformer.
