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:
Issue 01 (2018-05-03)
Protection against overvoltage of input power
Protection against undervoltage of input power
Protection against overvoltage of output power
Protection against current-limiting of output power
Protection against short circuit
Protection against overtemperature
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.
