EDIT: I wish I knew how much power this thing uses. Anyone have any experience with touchscreens? On average, how much power a 12" panel would use? I'm just going to buy
one of these: http://search.digikey.com/scripts/DkSea ... =SC1050-ND
and a power supply from: http://www.mini-box.com/s.nl/sc.8/category.13/.f if I don't have one laying around.


I bought this from eBay and I have no idea what this connector is called. It says the screen was likely mounted in a police car and that it runs on 10 - 40 volts DC. I'm sitting here wondering why there are three contacts if it were meant to run in a car. Does anyone know what this connector is called?

Getting a picture from my phone to here is a bit of a hassle so I'm hoping someone can just figure it out from the description. It's like a female PAL connector only with three holes in the center instead of one and it screws on.

Is there any serial number on the touchscreen?
I think the connector has 2 voltages, 5 volt and 12 volt (5 for LCD/Touch and 12 for backlight)
Can you maybe give the link to the Ebay page?

There is no manufacturer or model number anywhere on the case. I took the back off and it looks like someone has done a good job of putting some standard components together on their own. The panel is ELO. There is a DC/DC power supply inside that takes an input of anywhere between 10-40 volts along with another two PCBs and the panel itself. Only two of the conductors on the connector are being used. I was just hoping if someone could at least give me an idea about how much power this is going to use so I can find/buy a power supply for it.

We have ELO Touch Screens on POS Terminals @ work that use an external 12v Power Brick

maybe something like this:

Being as it was in a car, then it may be +12v, ground, and +12v switched (ignition/remote power on). If the device has some sort of volatile memory say for settings and such then it would need a perminent +12v supply and the +12v switch to turn the unit on and off. It more than likely only has an operating rating of 5-10amps provided there is not some type of power converter missing and it was wired directly to the car's loom in some way.
