N+N(AC/HVDC)
The NE40E-X16A supports N+N backup for PMs. The power supply system supports
the backup of power supply areas A and B on the user side. Every N power modules are
connected to one power supply area, ensuring that the entire system can work properly if
any power supply area fails.
The NE40E-X16A has four PEMs. Each PEM has four inputs. There are altogether 16
inputs (8 inputs in each of area A and area B). Each PM has two inputs. The two inputs
are from power supply areas A and B, respectively. In this manner, power supply areas A
and B back up each other. A maximum of 16 PMs can achieve a maximum of 8+8
backup. Figure 1-60 and Table 1-75 show the mappings between PEMs and PMs.
