Soft Start/ Stop Function - Kikusui PWR401L User Manual

Soft start/ stop function

You can set the rise time and fall time of output current.
This is useful when the load cannot follow the sudden rise or fall in the output current or when
you want to avoid the overcurrent protection from being activated.
Set the soft start time (CF04/ CF06) and soft stop time (CF05/ CF07) CONFIG parameters.
The soft start and soft stop times are applied to the operation mode set by the output-on
startup state (CF02: CV/ CC).
When you set the this function, SS lights.
When soft start is in effect, SS blinks, and the OUTPUT LED lights green.
When soft stop is in effect, SS and the OUTPUT LED blink green.
If you press OUTPUT when soft start or soft stop is in effect, the process is canceled, and the
output is turned off. If you press OUTPUT again, soft start resumes.
If the bleeder circuit is set to off, the output current may not fall gradually even if soft stop is
used.
