Planar 10.4 Powering

**bosstone74** · 09-19-2002, 01:40 PM

I have a 10.4 Planar LCD, I wish to power it only using the car itself, (no inverter, which i'm trying to move away from now). The power pack that it comes with says 12v 5v and a ground DC.

How would I go about making this to run directly off the car?

Thanks for any help!

I have always been told never to run the LCD or computer off of an unregulated power source such as the car. It makes sense to me...I am not an electrical genius of any sort so I have just decided to use an inverter which seems to work just fine. I am going to run the accessory line/cig lighter to the back of my trunk so that way the inverter is not in plain sight.

I actually have done this already, I'm going for the smallest possible install possible.

I know not everyone with a LCD in there car has an inverter powering it, so I was looking for that solution.

thanks

Well you are doing better than I am

Good luck on it and be sure to take plenty of pictures and put up a website for me to look at...hehe

If it needs 12 and 5 why not just wire it to one of the drive power connectors on the DC-DC AT/ATX supply I assume you have for your PC power?

seems like a good idea, but after I measured the amps coming out of the power pack, and then measured the amps coming out of the pc power supply the didn't match up...
and I already have to send in one of my LCD's for repair because it fried something out doing it....

so I was wondering if anyone else out there has hooked up one of the planar 10.4 LCD up to a power supply of some sort, but just not an inverter, and how they did it

thanks

You should be able to hook it up to the power supply of your computer, just make sure you get the voltages right. Most LCD screens don't draw much current at all, so it shouldn't be a problem. You said the current the power supply and the wall pack put out were different... how did you measure this? Current isn't a matter of output, it's a matter of how much a particular load draws from that output. If you're measuring current, you need to attach the multimeter in series with the power supply and the LCD, so the power flows through the multimeter.

and make sure you dont short the multimeter between +12 or +5 and ground with it in current mode unless you want to buy a new multimeter or at the very least put a new fuse in it

ok i just hooked my planar up to my psu an d got it all working
yellow +12V
red +5V
white +5v
blue RTN
no sheath = gnd

ok this is what i did
joined the red and white and connected them to +5v
conected the yellow to +12v
joined the rtn and gnd and connected them to the gnd
all pwered up and works fine.. hope this helps
