Programmable Power Supply Kit.

Posted: March 20, 2013 by kwood94xj in Bench Tools

Recently I was in the market for a new adjustable power supply. I searched all over for reasonably priced full featured PSU. I was considering going the hacked computer PSU route, but with its voltage maxing out at 12VDC it would not fill all my needs. Then I stumbled on this kit. It is a very well designed board based on a Atmega8 chip.

It features

  • A 16×2 LCD that displays the set voltage and current. it also displays the actual voltage and current.
  • A 5 button control interface to set the voltage and max current. There is a Store function that will save the current settings and re apply them on power up.
  • You can build it in many different voltage and current configurations. (22VDC 2.5A or 30VDC 2.0A are the standard configs)
  • Very low part count and all the components are through hole making it easy to assemble.
  • With the optional DDCP to USB kit you can set the output voltage and current with your PC via USB

The price of the kit is also very attractive at $31.99 it is a bargain. All that you need to add is a Atmega8, an 16×2 LCD, Heatsink, Transformer/Rectifier, and a Case.

The DDCP to USB kit that allows computer control is only an additional $17.20

I will post pictures of it in action along with a full review when I have completed the build.
