In 1+1 active/standby
power supply scenarios (AC
+AC, AC+HVDC, or HVDC
+HVDC), the PSU output
voltage is greater than 11.4
V, 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, in the case
of removal/insertion,
power-off, or faults (input
power failure, input cable
removal or insertion, input
undervoltage, input
overvoltage, fan fault,
overtemperature, or output
slow overvoltage) of any
power supply.
Note: In a 1+1 parallel
system, if the total load is
less than 70% of a single
PSU, one PSU restarts due
to overvoltage. In this case,
the PSU output voltage is
greater than 11.4 V, 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.
