I have two devices I need to power. One is a CCD card and the other is a "bunch" of LED lights. The CCD card works with 12VDC and the LED lights work with 18 to 30 VDC. Originaly these devices were supplied with a 24V power source. Not sure if it was AC or DC ( I am guessing DC by the diagnostic chart I had for this setup)
The existing cable I have has 4 wires wrapped in foil and a drain/ground/shiled wire on the outside of those 4.
Two of the 4 wires are needed for the video feed from the CCD.
Can I somehow take 2 car batteries in series and split the voltage into two seperate sources using only the 3 remaining wires? I thought I could do this with a voltage divider and soon learned that this basic circuit just reduces the supply votage.
Reason I want to use car batteries is becasue they tend to last for a very long time when drawing very small amps. AND to top it off I am running 300 feet of cable between the power source and my devices.
TIA for any help.
