    how would i power an lcd like this?

    http://cgi.ebay.com/ws/ebayISAPI.dll...oDisplayType=2

    doesnt list voltage but granted it is correct voltage for a car how would i power it?

    edit: found out its 12V 3.75A

    could i run it straight off the 12v line of say....an opus psu?
    would i just cut the end off of the thing and strip off some insulation and attach? would i use the small rectangular ac adapter thing or ditch that (i think that gets discarded)

    thanks

    if its meant for 12Volt aplication, then you would just run it 12volts from the car battery......with a fuse inline ofcourse.

    You shouldn't wire it directly to your car. It may work, but given that your cars standard running alternator voltage will be about 13.8 volts that won't help it any (but you'll have to check the tolerances of the specific unit).

    However you also have to think of alternator dumps, you can easily get upwards of 300 volts in certain circumstances, which should be protected with a transient surpressor.

    I power a 12v 5.6" screen in my car from a reg circuit I built (you can see the circuit on www.stuffandting.com). This circuit protects my computer as well, but given your screen is 3.x amps already you won't power both off the one reg.

    Go to the Elo web site....see if the have the voltages there...
    it's probably 12v and a 5v
    both of which your computer power supply will have....
    it's not to hard....and I don't know **** about ****

    would the nearly 4 amps max out the 12v line on an opus though?


    (i already found its 12v 3.75A)

    ...but does the Opus regulate the 12v line??? Most of the other DC-DCs don't (Lex, Morex etc) and just pass the raw 12v feed straight through, so you're still giving 13.8 volts (or more) to your screen.

    I know with my money I wouldn't risk it...

    Sweet, then you're fine with that one. Obviously you may struggle with the screen and other 12v devices running off the same unit, but in terms of protection okay.

    But then this is uber expensive, uber-clever PSU designed for in-car use, not like the Lex/Morex that most people use.

    alright, so say i got the opus and this psu
    how would it be connected?
    just stripped on the end without the ac adapter and connected via molex or whatever to the opus 12v line?
