I’d like to apologies in advance if this has been answered in the past. I attempted several searches but could not find what I needed.
While I have 20+ years in electronic repair I have zero experience designing circuits.
I have been asked to determine the amount of output power required to operate three video cameras. Each camera will draw up to 7 watts when under full power. Each camera needs 1 watt and the camera heaters require 6 watts.
The output voltage provided by the display to each camera will be 10 VDC.
I also need to consider the cable length from display to camera, each being about 100 feet using 28 or 22 AWG multi strand copper wire.
My first thought is 21 watts by simply adding what is needed for each camera however when I consider the voltage drop along the cable I feel that may not be enough.
Any help would be appreciated.
