5-6 Soft-start Up and Soft-start Down Functions
The soft-start up and soft-start down functions are used to change the output
value gradually within a set rate of change, even when the input value
changes suddenly. You can set the time for the output value to go from 0% to
100% (i.e., the SUP (soft-start up time)) and the time for the output value to go
from 100% to 0% (i.e., the SDN (soft-start down time)) to a value from 0.0 to
99.9 s.
• Relationships between Input and Output Values and Soft-start Up and
Down Times
!Caution Specify the soft-start up time so that the inrush current will not be too large. If
the soft-start up time is set too low, the inrush current cannot be suppressed
and the load may be damaged.
