How to build a $20 47A power supply

[scarletboa]

is it possible to put two of those psu's in series? i am thinking about getting a icharger 3010 (1000w) and it supposedly runs best on 24v.

It can be done, but at a big, big, big risk... I would not advice it... you will need to remove the wall 'ground' on at least one of the supplies (if you don't, they will shot down when you try to connect them)... if this is done, the metal case will be 'energized' (a technical person can step in here)... meaning if both cases were to be come in contact, you will have a big spark/short... I tried with one ground removed and both grounds removed... you can actually measure the voltage between the two cases when both grounds are off (12v).

If you really need to do this, keep them both separate with some insulation... you will still be running a risking of damaging the supplies internals without them being grounded...

No, but you can use them in parallelel.

+ with + and - with -

So you double the amp.
