It is recommended that the time from when the power supply starts to fall to when all the power supplies are turned off should be within 100ms.

In addition, it is necessary to start the next group after dropping 10% or less between groups.
The shutdown time for each group is not specified, and it is understood that there is no problem as long as it is within 100ms in total.
