Designed for professional DIYers and tech enthusiasts, it supports constant current/voltage modes, easy voltage calibration, and comes with a protective case and USB output, making it an essential tool for precise power management in electronics projects.

## Description

If there's any problem, please feel free to ask us for more information. Parameters Input Voltage: DC 6-30V Output Voltage: DC 0.5-30V adjustable Output Current: 4A (max), adjustable, recommended to use within 3A. NOTE: If the output current or power is more than 2.5A or 35W, you’d better enhance the heat dissipation. Output Power: 60W (max), recommended to use within 50W. NOTE: Please reduce the power when the difference between input and output voltage is large. Operating Temperature: -20~+70℃ NOTE: Pay attention to the temperature of the power tube when using this module, please strengthen heat dissipation if it exceeds 70℃. Wiring: Terminals or solder terminals; VIN means input; VOUT means output. Protections Short circuit protection: Yes (currently constant current value) Over temperature protection: Yes (automatically turn off the output if over-temperature) Tips: There is an additional fan opening on the bottom of the module shell, which can be used to add a fan. Input reverse polarity protection: Yes Output anti-backflow: Yes Voltage Calibration If you find that the measuring values are not accurate, please do as follow: In the condition of power off, hold press the “SET” button and power on to enter the voltage calibration mode, at this time the LCD screen starts to flash. Then release the “SET” button, press the “SET” button to increase voltage value while press the “ENT” button to reduce, till the input voltage value is correct. e.g. If input voltage is 12.65V, adjust the voltage value to 12.65V. It will automatically be saved after 2 seconds, then power off the module to finish calibrating. Package includes: 1 x Boost Buck Converter Module; Components for the case (Nylon post *8; Screw *8; Acrylic board *2)

Review: Easy install and works great as an upgrade. - Bought a trail cam,built battery box for 12 volt dc jack,camera died in 2 days ordered different camera,this 1 turns out to be 6 volt,installed this guy which saved me from buying a 6 volt battery.Adjustable output voltage,usb port with adjustable out voltage,accuracy is great for my needs,draws almost no power,not much draw so heat is low and battery life has only dropped .02 volts in 2 weeks use.Lot cheaper than 8 AA alkaline s.
Review: Great voltage regulator - It works great

## Features

- Parameter --- Input voltage: DC 6-30V; Output voltage: DC 0.5-30V; Output current: 4A (max), adjustable, recommended to use within 3A; Output power: 60W (max), recommended to use within 50W. Note: This product is intended solely for DC-DC loads that do not incorporate computers or laptops.
- Easy to Read LCD Display --- The buck boost board is designed with a large clear digital LCD display on which shows both voltage and current value simultaneously. Which is easy to read and can help the user easily monitor the output voltage, then largely enjoy their DIY work.
- Application --- This voltage step up and down module can be used as a normal boost buck converter module with over-current protection, a battery charger, a high-power LED constant current driver module, etc.
- Features --- Constant current/voltage mode; Voltage calibration calibration; USB output; Protective case; Short-circuit protection; Over-temperature protection; Input reverse connection protection. You can find the PDF Instructions on this page -- Product information -- Product guides and documents -- User Manual [PDF].
- NOTE --- 1). Constant current adjustable means that CC mode only works when the actual load output current is greater than the setting one, otherwise it will work in a constant voltage state, not the current is adjusted to 2A, then it will become 2A for any load being connected. And if the CC value to be adjusted is small, adjust “ADJ-I” counterclockwise a few more times to change. 2). The case is packaged disassembly to avoid damage during transit. It needs to be manually installed.

### ⭐⭐⭐⭐⭐ Great voltage regulator
*by K***R on January 25, 2026*

It works great

### ⭐⭐⭐⭐⭐ Confusing at first
*by J***C on December 29, 2024*

The directions that come with it are virtually crap. Your best bet is to find a video like i did (unless you know and understand electrical operations, which i didn't). The wiring was very easy, but you need to build the housing, and hat ended up being the first nightmare as the directions were not helpful. The second, make sure you have a very, very, tiny flat head screw driver. As I even struggled with the YouTube video (a tiny bit), I decided to say "F" it and just start turning the screws. The left is the volts, and the right, as far I can tell is for... I dint remember. I just know I turned that one around 30 times before it did anything. That said, it works great. I'm running an old laptop power supply to my HO train set. As it is putting out 19 volts, I had to get it down between 12v and 14v continuous power. It works perfect for that. I'd buy it again.
