Bench Power Supply

[TheJay]

Hey there, I have a number of projects where I want to convert battery powered stuff to mains/want to be able to test my projects as I work on them without connecting batteries to them.

At the moment for example, one of my projects involves 12v lights. I don't have any suitable batteries and would rather connect to a steady supply whilst testing.

I'm thinking about getting a bench power supply. What would I need to look out for? Can any deal with AC and DC? How many amps? Should I be looking at something supplying more than 12v? Can deal with series and parallel? I'd like something with a digital display.

Lab supplies are cheap these days with 3 digital displays for V, I , Pwr.

For free, you can find an old 350 W PC PSU with 12, 5, 3.3V
