  • AC-DC 12V 5A adapter for my DC-DC ATX PSU

    I am looking for a small AC-DC adapter that gives at least [email protected] for my carputer with DC-DC PSU. Anyone can recommend one?
    I want something small that I can leave in the car when i use the carputer for a party and such... I have a benchtop PSU that
    s [email protected] but its too big to carry around, and a computer AT/ ATX type power supply is just too big n ugly =p

    anyone?

    How about a small computer supply? Grab one from an AT slimline case. Probably as small as you are going to get. Standard "adapters" are liner, meaning they have a friggin' huge transformer. For 5A at 12V, this would be about the size of a baseball.

      I use a 3A supply that is pretty small. Here is a link to it. It powers my carputer quite well. That pic is stretched too. It actually looks like this. It doesn't show in the picture, but there are Push-Terminal connectors so you can connect bare wires as well as lighter size plugs. Dimensions (HWD): 1-7/8 x 3 x 7-1/2 Inches, Weight: .89 lbs

        I just measured the current draw on my carputer and it peaks at 5.4A @ 13.8V I guess I would have to get something like this: http://www.mpja.com/product.asp?product=12417+PS

        Anyone know why the output on the adaptor above is 5 DIN? It seems to be for a laptop of some sort...what are the other 3 pins for? ( i assume there is one for + and other for ground)

          At that price you can buy it and use your multimeter to find out. should be pretty easy to isolate the power and ground wires and put any kind of connector you want on it.
