Here is some specification for cable design power supply unit (PSU):
Pn = 78W
Power consumption of N2RU
Pw = 22W
If N2 consumes 95W then 5W is dissipated
in the wire (Pw)
Pin = Vin*Iin = 100W
Pin = 100W max for class 2 installation
Rw = Pw/Iw2 = 6.8992
Rw = resistance of the wire
Vin = 56V
Voltage of N2 PSU
Rw = Rd*D
D = distance of the wire (total length of
return cable)
Rd = resistance per meter of the wire
Iin = Pin/Vin = 1.786
Iin = Max injected current to not exceed
100W
