The AC power system supports 200-240 V AC power. It supports 110 V dual-live-wire inputs but not
110 V AC single-phase inputs. If 110 V dual-live-wire inputs are used, the voltage must range from 180
V to 264 V.
1.8.2 NE40E-X3A Power Supply System
1.8.2.1 Architecture of the Power Supply System
The NE40E-X3A supports either DC or AC power supply.
Power modules convert the input voltage into -48 V DC voltage to supply power for the entire
system. The power supply system has the following features:
