Power Suppy 12v - 13,8v

levieleuterio · 26th July 2011, 08:30 AM

Hello. Sorry my bad English. But I'm going right to the question: Can anyone get me a diagram of a source 12 to 13.8 V with 40A, simple? (Scheme and dimensions of the plate (copper part and the hole where you owe yourself the componet))

I want to connect a source not in the car but in home

You could use a transformer out of a non working PC computer UPS.
I have done this and have gotten about 40 to 50 amps out of one rated about 500 watts or so.

Or modify a PC power supply.

well you didn't say that... best bet for you is, transformer and linear regulator with pass transistors

A battery works much the same whether it's in a car or in a garden or in a house.

A 12V battery is a 12V supply.

Here is a switcher if you need something that plugs into the wall. 115VAC/230VAC switchable. Free ship worldwide it says...

Or find an old dead microwave oven,and re-wind the transformer. It's crude,and ugly,but it works like a charm!
