V
In 2+2 active/standby
power supply scenarios (AC
+AC, AC+HVDC, or HVDC
+HVDC), when the
following faults occur, the
PSU output voltage is
greater than 11.4 V, and
the PSU 12 V bus voltage is
greater than or equal to 11
V and the time when the
bus voltage is lower than
11.4 V does not exceed 100
µs.
1. One power input fails
(2+2 backup, one power
input for two PSUs).
2. One PSU becomes faulty
(such as input
undervoltage, input
overvoltage, fan fault,
overtemperature, and
output overvoltage).
Note: The 12 V output of
parallel PSUs is equipped
with 1500 µF capacitors.
