DROK DC-DC Buck Converter Constant Current&Volt Regulator 5-36V to 1.25-32V Step Down Regulator 5A 75W High Power LED CC Driver Board, Battery Charger for Solar Panels/Wind Driven Generator

Input voltage : 5-36V (the input voltage should at least 1.5V higher than the output voltage)
Output voltage :1.25-32V (continuously adjustable,default output 17V.)
Output Current : 5A MAX(Please use it within 4.5A)
Output Power: Max 75W (Please use it within 50W. if the pressure difference is big,please reduce power)
Operating temperature: -40 to +85 ° C
Operating frequency: 180KHz
Conversion efficiency : up to 96%
Short circuit protection: Yes
Overtemperature protection: (automatically shut off the output after overtemperature)
Input reverse polarity protection: No, (if necessary, please in input
String into high current diode)
Installation: 4pcs 3mm screws
Wiring:(solder terminals) V-IN is the input, V-OUT is the output

1. Use as an ordinary buck module with overcurrent protection capabilities;
2. Use as a battery charger;
3. Use it as a constant current LED driver module.

1. If the module can not be adjusted, the output voltage is always equal to the input voltage.” When you encounter this problem, please counterclockwise rotation of the potentiometer 10 laps or more, then you can adjust the output voltage. Because the factory default output voltage is 17V.
2.Module output terminal string has a current sampling resistor, there will be 0-0.2V voltage drop after connected to the load, it is a normal phenomenon.
3.If its output is more than 3A/35W, please enhance heat dissipation!

4.This DC converter is single output, the output voltage of the USB port is the same as the output voltage of the module, if your load is USB device, please make sure the module’s output voltage is set at 5V.

Package include:
1 x Buck Converter

  1. Nice Looking Regulators that do exactly what they were made for This buck volt regulator added a nice touch to my back-yard lighting project. It allows me to tweak a 12V camera power distribution box down to 3.5-6v depending on how much I want to strain my light strands. I’ve been using it nightly for several weeks now.The case assembly was easy enough and amusing. The voltages are pretty dang close when I use my multimeter so I didn’t bother with calibrating it. It does everything I need!The board with the case came with case,…

  2. Satisfied customer. Does what it’s supposed to, except when supplying it with a 5 volt source it was reading about 6.4 volts and I couldn’t adjust it any lower. When supplied with a 12 volt source it was more accurate with displaying the input voltage at 11.9 to 12 volts, and the output voltage was displaying the same input voltage. To change what is currently being displayed when running power through it I held down the right button for a second or two then released, whatever was being displayed would start…

  3. I’ve been playing around with the DROK 5A LM2596 voltage regulator with a 12V, 110Ahr deep cycle wet lead acid battery used on my boat trolling motor. This battery is like a large car battery. It WILL NOT charge a depleted battery. A 200W charger would be the minimum requirement to charge this battery. This DROK is good for about 40W before the regulator becomes hot without additional cooling fans. I’ve produced 60W while cooling it with a fan but didn’t feel comfortable pushing it beyond that…
