Automatic Restart
When the supply voltage recovers to a value higher than 85% of the rated value,
operations resumes automatically.
Duration of power interrupt
(Below 85% of rated voltage)
10 ms (2 ms)
Under Over
Normal operation Operation may stop.
All outputs go OFF when
operations stop.
Note The CPM1 may repeat stop/start operations if the supply voltage of less than
85% of the rated value gradually goes up or down.
If this affects the equipment, etc., provide a protection circuit which shuts off the
output if the supply voltage is not above the rated value.
Time Up to the Start of Operation
The time from when the power supply is turned on to when the operation starts
varies depending on the operation conditions such as power supply voltage,
configuration, ambient temperature, etc. The minimum time is approximately
300 ms.
