These devices are great for long distance power, simply run the standard 24vAC power over the CAT5 cable and convert back to 12vDC at the end of the run. This solves problems with variable voltage on IR and mechanical cameras. The converter will take anywhere from 18vAC - 28vAC this allows for a much larger voltage drop and the ability to maintain your 12vDC power. Input Voltage: 20-28vAC Output Voltage: 12vDC ± 2% Output Current : 1.5A 1 port, 1.5A output current Output short circuit protect Overload protect.
