  • Powering an LCD monitor

    I will be assembling a mini ITX computer to install in my sailboat. It's main purposes will be navigation and picture editing. For navigation I intend to use an eight inch Lilliput with touchscreen while underway but would like to use a conventional LCD monitor while at anchor. I would like to avoid using a 12v to 110v inverter since they are tend to waste a lot of precious battery power. Is there a way to power an LCD monitor from my battery bank without the aformentioned inverter? Also, I plan on using a Casetronic C134 case since they are aluminum. Are there any other suggestions for cases?

    What kind of LCD are you trying to power? Most LCDs are 12v. You hook them up to the yellow and black wires of your PSU.

      depending on the the size (and the rest of your computer system) an LCD may draw too much power for many DC-DC PSUs. You could of course get another PSU just for the monitor, or better yet a good 12V regulator since the LCD isn't going to need the other voltages a ATX PSU provides. This is assuming the panel in question takes 12V of course.

        Casetronic makes solid cases. A 7" screen needs a little less than 1 Amp, so no question about having a separate PSU only for the screen...

          at most you can guild a very simple regualator if power is tight. YOu just need about 1200mA to be safe but 1A should do it. Normal draw is 10W MAX on a 7" LCD.
