  • need a voltage regulator

    hi all

    i think i'm going to go over my opus' 90W power rating (well soon, if i keep adding stuff). i was wondering where can i get a small and compact voltage regulator for +12V. thanks.

    What are you going to power off of it? How many amps will you draw?

      i have a opus 90. i'm currently running my liilput, my epia computer, a 80mm fan, using it to power a slimDVD, GPS, external hub, usb NIC. It's also powering the remote lines of my amp and equalizer

      i'm planning on adding a SB audigy2 and a Wintv USB PVR to it.

      So i was thinking i could put the hub, WINTV PVR, SB Audigy on the line with the regulator. what hardware would i need for that? Thanks

        Well, first of all, that mostly 5v, not 12v

          all of it is 12V except the WINTv USB (that's only 6V) i would still use a +12V line for that and get converter (forgot what it's called) to convert the 12V to 6V... i have it done for my homemade garage remote control.

          i'm just concerned that i'm drawing too much from the opus, and want to just use another source to power the peripherals. check out the pic.

          Basically i need a regulator that will just keep the voltage within 12V -/+ ?V (just to keep the sensitive electronics happy) I don't need a shutdown controller or anything because the relay(opus powered) will turn on and off the devices.

          So here's how i plan it'll work. I turn on the car, the opus powers up and then 'LineA'(HDD molux power cable) will trip the relay and that will let the regulated power go to the peripheral electronics.

          I just need to know where to get a nice compact voltage regulator. Thanks

            Why don't you check to see if you're exceeding the power specs?

            Try these power calculators I found from searching on "power calculators":

            http://www.mini-box.com/powersimulator.html
            http://www.jscustompcs.com/power_supply/
            http://www.mymp3car.com/MP3Car/PSUpower.asp

            You may find out that you aren't exceeding the specs and don't need to go through the effort. Your biggest power draws are the Epia and the Lilli and it falls off pretty quickly from there.

              I know that these are low-draw items, but the fan definately does not need to be ran off of the clean 12v supply, the hub probably does not need exactly 12 either (but not sure on this), and the remote lines, why not run them from the head unit remote on?

              I put one of those computer fans on at around 50 volts once, and believe it or not, it held up. Got too close to it though, and it bit me!

              Like I said, this doesnt really save you any power, but may as well not put on extra stuff that you dont need on the clean 12, you know?
