Note: The maximum power consumption is 98 W when N2 has 8 PA modules operating at maximum
output power.
Class 2 Installation for North America area (maximum input power is 100 W):
Pn = 78 W
Power consumption of N2RU
Pw = 22 W
If N2 consumes 78 W then 22 W is
dissipated in the wire (Pw)
Pin = Vin*Iin = 100

Pin = 100 W max for class 2 installation
Rw = Pw/Iw2 =

Rw = resistance of the wire
Vin = 56 V
Voltage of N2 PSU
Rw = Rd*D
D = distance of the wire (total length of
return cable)
Rd = resistance per meter of the wire
