how can i convert one 24v dc output into two 12v dc outputs? Answered
i am making a psu for my cctv system. i have a fairly new psu from a fire alarm panel which has battery terminals so it can still supply power even if the mains is out.
my cameras can run on about 9-24v but my DVR needs exactly 12v 5a.
The most logical thing to do i guess is convert the 24v output from the psu into 12v that i can then fuse off to go to different cameras and the dvr.
trouble is i don't know how to. i thought of a voltage divider but it turns out they are bad if using more than a couple of Milli amps.
would a voltage regulator do it?
i'm abit stuck here so any help at all would be brilliant. thanks - luke
