6.1 ON/OFF operation
Three ON/OFF functions are available with the CHS300/400/500 as shown in table 6-1.
in order to control starting-up and insulating power supply by external signal.
When either setting is "OFF", power supply will be stopped.
*1: When operating by positive logics, it is optional.
*2: When invalid setting is made by command, it will be status of "ON" compulsory.
6.2 Start-stop voltage
Power supply is started-up when the input voltage exceeds set value of VIN_ON [ 35h ] (*1)
and is stopped when falling below set value of VIN_OFF [ 36h ] .
When changing a set value with start-up voltage and stop voltage, have an equal to or more
than 2.5 V hysteresis between VIN_ON [ 35h ] and VIN_OFF [ 36h ] to avoid the operation
which repeats a start-up and a stop.
*1: Be sure to set VIN_ON [ 35h ] > VIN_OFF [ 36h ]
