  • 12vdc power regulator

    Is anyone using a 12vdc power conditioner? I use to see these in car stereo business where it filters the power for a clean 12vdc, no spikes. Think I need one for a carputer? Don't want to have power spike kill my carputer.

      My equipment is all 12vdc (laptop, display, etc). Avoiding the ac-dc converters. Think it would be a problem if I left my laptop on all the time. Just connect the screen to switched 12vdc. That way I have instant on without boot time =)

        whether or not you need one for your car pc depends. If you're using a viaM10000, and a power supply like the PW-xx series from minibox ... and if you don't have any 12v components ... then you don't need one.

        Other wise it's a darn good idea. There's a number of schematics available on this forum and on the internet (including mine when i get off my lazy duff and draw one) that show good designs ... most of them use the LM1084-IT12 regulator.

        You can also just use MiniBox's ITPS ... which has a regulator in it.

          in this case you definately need a regulator.

          leave your pc on all the time??? your battery would die in a matter of hours.

            Thanks shakes =) I think the power won't last either. I will plan to wire everything to a switched circuit that goes down when the acc is off. Not sure if my laptop will wake from sleep with just a touchscreen input. I would like to avoid using my keyboard.

              you should be able to wire some sort of shutdown controller (like the ITPS) to the laptop's 'sleep' button.
