How to build a $20 47A power supply

[Metallover]

I decided I would go about building a 24v power supply. There's a guide on hooking up two power supplies in series here.

I got my power supplies from ebay yesterday and wired em up today. Now I have a 24v 1150w power supply that I paid $26 for.

The final unit is 13x7" and the output measures 25.2v. If I put the leads of my multimeter on each power supply, I get 12v between the two. I haven't touched it yet, and I don't know if it will shock me if I touch it.

I cut some pegboard to mount the power supplies on.


Testing - The power supply on the right is wrapped in clear packaging tape.


I mounted the power supplies to the pegboard with some bolts, M3 I believe. I then used some unshrunk heat shrink (1" wide) and duct tape to try to insulate the screws.


And my awesome duct tape job.
