Cheap power supply for a begginner going on "FleEbay"?

On the switchers I tend to just buy a meanwell unit from RS for the task at hand. Those are pretty good and don’t explode if you short them out. The same cannot be said for the DUT :D

LOL... poor DUT!  :-DD

I dunno how durable the Ebay one I have would be. I doubt it would handle as much "beginner" mistakes as the Tenma 1 has over the time i've owned it. It has probably ended up costing about the same £'s as the Tenma 1 when you add all the pieces together. I kinda bought it a piece at a time after i watched a few YouTube videos on it. I had no intention of building the finished unit when i bought the first power supply board, then the control unit, then the case, then the seperate PSU to run it from the wall...  :)

I am after power supply as well, but what to go for if I need to test car components. So I need here around 12/24V with current up to 24A or so.
Any suggestions?

rsjsouza:
A car battery perhaps?

In a very distant past we used to have a couple of motorcycle batteries when we needed some real output current at that voltage level (at that time switching PS was almost non-existent and linear was very expensive).

Yeah I use one now. 28Ah SLA does the job.
