NE20E-S2F V800R009C10, In order to improve power supply redundancy, Customer want to provide 1 AC supply and 1 DC supply at the same time.
The NE20E-S2F has two power supply models, AC power supply and DC power supply.
The hybrid power supply will report a power mismatch alarm.
And if the two-way power supply is not the same, there will be a voltage difference between the AC and DC power ground. If the voltage difference is large, the device may be damaged.
Conclusion: NE20E-S2F can't work with 1 AC supply and 1 DC supply at the same time.
