Parameter
Hot swap
NO TE
● Specifications are subject to change without notice.
● Short-time output power of MV12: V
W, the PSU does not trigger protection within 2 minutes if the output power of the PSU is switched to 2200
W transiently.
● When the PSU output voltage is less than 4 V, ignore the power-off ringback. When the PSU output voltage
ranges from 4 V to 9 V, the power-off ringback is less than 300 mV. When the PSU output voltage is greater
than 9 V, the power-off ringback is less than 400 mV.
● Active current sharing is used for the parallel system.
● Current sharing imbalance applies only to the normal temperature.
● Requirements for switching the output modes between MV12, SV12, and MV6:
●
PSON12V# is at high level, and the PSU output enters MV6 mode.
●
PSON12V# is at low level, and the PSU output enters MV12 mode.
●
When PSON12V# is at low level, the PSU IP PRESENT# works in the following modes:
●
IP PRESENT# is at high level, and the PSU output maintains MV12 mode.
●
IP PRESENT# is at low level, and the PSU output enters SV12 mode. The indicator blinks greenat 1
Hz.
●
IP PRESENT# signal detection validity time is greater than or equal to 25 ms, and the switching
delay time is less than or equal to 200 ms (including the detection time).
● In the parallel system current sharing scenario, fault isolation (except output overvoltage isolation) is
performed. The upper threshold of the 12 V output busbar voltage of the PSU is 12.8 V.
● In a parallel system, the upper threshold of the PSU 12 V output busbar voltage is 12.8 V for PSON12V#
switching.
