I have a video monitor that requires + or - 5% of 12DC ........do you guys know where to get or make a 12volt regulator ? Hate to spend this much money and then blow it up ! My car system is pretty much at 14V constant. But the manufacture claims that it will damage monitor.

 

What did you buy, where did you get it, and who told you something as stupid as that?

 

you could use two voltage regulators one + one -
or buy a premade on the only thing is they probably won't have filtering to deal with your electrical system

look up 7805 regulator and it will have a negative sister with a similar number

 

I guess this screen wasn't designed for a car then ?

look for a regulated DC-DC supply that holds 12v...

 

or simply return it and buy one thats made for a car like an alpine clarion and other brands

 

its a Sharp 21" LCD monitor only..............and thanks for your help !

 

Thanks Pinhead i will check out that info. Appreciate the help
