non-conventional install and power supply

**jersey** · 05-29-2005, 09:49 PM

Hello all.

Looking for some guidance with my non-conventional install.

I am looking to use lcd's in a gallery show I have coming up in several months. The lcd's will be housed in custom aluminium / powdercoated / stainless cases (havent decided which yet) and mounted on articulating arms.

The issue I am having is powering these things. Can I simply use 2 of These
or do I need regulators, resistors or anything else? can I simply plug these into the wall and forget about it?

any help is greatly appreciated.

Heres what I'm running

best,

Well, if I'm not mistaken, the LCD has a Power consumption of 0.8 Amp according to the specs. As the power supply is rated 15 Amps, you could theoretically power 18 LCDs from one PSU.

Can I simply use 2 of These

Well, if you want to power 36 LCDs, yes :-) : 18 on each (don't ever connect the power supplies outputs in parallel).

The only thing you may want to add is one in-line fuse near the power supply for each wire going to an LCD. Although the PSU is protected by a fuse too, that will make sure your lines don't overheat in case of wrong wiring, and if one line is shorted, the other ones will still be powered... 1Amp fuses should be OK. (If the power-on peak blows the 1Amp, try with 2Amp but I wouldn't go higher)

Before you forget about it, test your setup with a single LCD, check voltage and current, then proceed with the other ones, and finally let the whole setup run for a few hours, regularly checking that nothing overheats (PSU, LCDs, power connections, ...), and off you go !

Thanks for the help vicne. I just wanted to make sure i wasn't going to toast these things right out of the box.

yeah i thought the psu's were a bit overkill, but i couldn't seem to find anything lees that accepted bare wire.

i will put a fuse between the psu and the screens, as suggested.

thanks,

just as an update i went with 2 of these (not so much of an overkill now) and added 2amp inline fuses.

now once the screens get here.......

so......

got the 2 screens friday. hooked them up today, and the power supply worked well. ran them for an hour nonstop and all was nice and cool.

spent the last 2 hours ripping these things out of the housings. the flip-down is a pain in the ***. however got 1 done. and simply as an FYI they are running casio screens.
