This adjustable DC regulated CC CV power supply DIY kit is a great power supply solution for beginners of DIY electronics. You can also learn soldering as this kit requires the user to solder it before using. All the components are provided in this kit and the user can solder them by following the names of the components printed on top of the top quality PCB (2nd image). Just get a 12V transformer (24V p-p), solder the kit and you'll have your self-made 0-30V DC and 2mA-3A adjustable CC CV power supply.

Q: Spec says The input voltage: 24V AC is it right? Questioned by rezwan, 31-Dec-2016

Yes. Answered by A.R, 01-Jan-2017 10:25 AM

Q: If i supply 12V to this board wii it work? if we supply 24v 6A what will happen? Questioned by mbaksh, 12-Dec-2017

The input voltage: 24V AC Input current: 3A max So, this should be maintained. Answered by A.R, 13-Dec-2017 10:27 AM

Input current: 3A max It's a garbage mention. Forget that I think you should supply almost 4A when you draw 30V 3A at the output. Answered by mtr.eee.sust, 26-Jun-2018 19:55 PM

Q: If I supply 12V to this board will it works? Questioned by mbaksh, 12-Dec-2017

Q: Does this have Constant Current and Constant voltage(CC&CV)? Questioned by tausif, 01-Apr-2018

Yes. Please see here: Answered by A.R, 02-Apr-2018 10:42 AM

Q: Max output 30V, 3A (means 90W)... input 24V, 3A (72W). MAX input current is 3A .Doesn't make any sense!!! By the way their is no need to specify max input current, it will automatically determine by output load. Questioned by mtr.eee.sust, 26-Jun-2018

Thank you. We mistakenly wrote that. Corrected. Answered by A.R, 27-Jun-2018 11:38 AM
