    I love these supplies. I used them to build a variable DC supply for my bench. I changed the pots for panel mount 10 turn pots and fed these supplies(3) with a high current 24V supply. Most of the parts for this project were source from banggood including the laser to engrave the front panels.

    Incredibly small but very good! Order arrived without delay and without problems, nothing damaged and well packaged. I have already tested and was very pleased, I put in the entrance 22 Volts DC taken from my source and was regulating the output and took several voltages as you can see in the photos. So I recommend it, it didn't heat up and finally I say it's a good regulator from DC to DC. We must be careful not to exceed the maximum voltage allowed by the manufacturer. Thank you Banggood

    this voltage and current converter is Ok. it works properly. I have no problems with it. only need to replace the controllers for rotary and larger. I am satisfied This convert and converter is Ok. works together. I have no idea with it. it is only used to protect the ingredients with rotary and chemical uses. I am protected

    Good stuff! One heatsink gets real hot though when (in my case) input is 19.5 volt to output 12.6 volt @ 4 amps. Installed a fan to fix it.

    A good Step Down module, that can regulate Voltage and Current. Not the first time I use this product. Notice that the functions of the pot are not indicated on the board. With a voltmeter it's easy to see which one is for voltage and which one for current. Be careful, mine has one power transistor isolation pad not really fully covering the heating. The screws were not tide too. I will recommand a little inspection before use. The two 10 kohms pots can be replaced by external one if you need.
