Here is a Power Supply I use for my Arduino Projects. It is a 24v 5a MeanWell and two POWER SUPPLY MODULE M2L8 from ebay. I stuffed it into an old case. Total cost was under $70. Fits perfectly under my Fluke 45! |

Transformers alone will probably get you close to the price of a chinese power supply. --- End quote --- nice job on this. i do agree on your statement though its definitely not cheaper to build I could have bought at least one used HP off ebay by now with what Ive spent on parts for my PSU. but I'm building it as a project to learn so from that aspect I think its worth it I am learning a lot. |

A radio shack 12v 'Battery Eliminator' with a chinese CV/CC module in it. Hard to end up with a smaller package on your desktop and still have CV/CC, although I doubt that without better cooling its ability to provide more than about an amp. |
