## Description

Product Features Parameters: Input Voltage: DC 4-38V, error ±0.1V Output Voltage: DC 1.25V to 35V Output Current: 5A(MAX) It is recommended to use under 4.5A (NOTE: When using high power, add a heat sink to the power supply chip) Size: 6.6x3.9x1.8CM Weight: 22g Fuction: Built in over-temperature protection function Built in current limit function Built in output short-circuit protection function How to use 1.Press the left button so that “in” LED lighted, the voltmeter shows the value of input voltage 2.Press the right button so that “out” LED lighted, the voltmeter shows the value of output voltage 3.Rotate the top screw of potentiometer clockwise to boost the value of the output voltage, anti clockwise to reduce it. How to adjust accuracy of input/output voltage (for the person who need a highly accurate value of number） 1.When the voltmeter shows output voltage, long press the right button for 2 seconds, then release, voltmeter and “out” LED flash in synchronization entering into the output voltage calibration mode. 2.Press the right button, the voltage value rises a unit; Press the left button, minus a unit ( Due to a unit is less than 0.1V, so you have to continuously press 1 to 5 times to see the voltmeter change 0.1V) 3.Press the right button for more than 2 seconds and then release to exit the output voltage calibration mode. All parameters will be saved automatically.

## Features

- Input:DC 4V to 38V ( input voltage should be 1.5V higher than the output voltage)

## Customer Reviews

### ⭐⭐⭐⭐⭐ ... just received 2 of these and so far so good. They have a nice look to them
*by R***N on November 22, 2017*

So I just received 2 of these and so far so good. They have a nice look to them, plenty of led's to indicate their functionality (power on, input, and output voltage modes, etc.), and the voltage display reads well! I have tested the two I received with a DMM and the display is quite accurate (it is accurate to .1 v so if you have 7.65v actual it rounds up to 7.7v). The potentiometer takes a few turns to adjust, but once the voltage begins to move it moves quickly. I have yet to try out the .01v fine adjustment process using the buttons as it is not that critical for my application... so no comment there.All in all this is one of the best $6-7 (each) I have spent on amazon,--works as promised and they look neat. Time will tell the story of reliability, but for now I think these are just awesome!

### ⭐⭐⭐⭐ Put the heatsink on it and don't overdrive it for long periods.
*by S***N on April 21, 2020*

Bought three of these so far I like them but one of them I was pushing it a little hard and I have the heat sink solid on the transistor but the diode the little square rectangular black diode on the output side just went poof burn to Ash when I was over driving it a little bit maybe but we'll replace it and see how it goes still have two that are working flawlessly. I wouldn't recommend running these at 5 amps I'm not sure I even quite got that pretty close though.

### ⭐⭐⭐⭐ Great little converter!
*by B***S on November 11, 2019*

I am using this to step down a 24v supply to 12v to run some fans (hotend and part cooling fans as well as a fan for the buck converter and the 3D printer driver board). Very stable. The only issue I have is that the LED display stopped working after being in service for a while. I can't see any damage to the board and the output is still rock steady at 12.03 volts (according to my trusty voltmeter). So, it's still functional, just no display - bummer :-(
