*Please Read. (SPECS below) Here is my quick set up and usage tips. One of my Freego, China Segways runs on 72 volts and have no stock lights. The others run on 36v, but do have their own lights.
I needed something quick and inexpensive to convert ½ of the 72 v battery of 36 volts to run 12 v LED Lights.
This Drok LM 2596 Buck Volt Regulator tells input voltage, output current, has a USB Charger, and works perfect. I do not typically read reviews when I do a project, so not to be biased. My findings are strictly my own. Sometimes I will read reviews after I make mine. In this case I did, and found one fellow said the case does not have the legs cut right. Okay, there are no instructions and the case is a puzzle. Each piece which is precision cut will only fit one way. So turning inside out, upside down, until you get it takes some patience. All complain there are no instructions, which is true, but if a person was going to use this, he would easily figure out from the picture and the printing of how to make it work. Hopefully my video will give you an insight of what you can do with this neat gadget that costs under $10.
DROK® LM2596 DC Buck Volt Regulator 36V to 24V 12V 5V 3.3V 3V Converters Constant Voltage & Current 5-36V to 1.25-32V 5A 75W
Parameters:
Input voltage : 5-36V
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
Over temperature protection: (automatically shut off the output after over temperature)
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
Usage:
1. Use as an ordinary buck module with over current protection capabilities;
2. Use as a battery charger;
3. Use it as a constant current LED driver module.
Note:
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!
Thanks for watching and I hope you enjoyed the flights
