pervision circuits for the dynamic and static comparison of actual
value and set value.
Supervise step: Default: U→Uo

value and actual value of voltage

= 5.00A Allowed tolerance for the current
The settling process of the power supply is determined by the
load. After a set value has changed, a certain time elapses until
the desired value is put to the power output. For instance, it can
last some seconds for the voltage to go down from 100% to 0V at
no-load operation, because the output capacitors need a certain
time to discharge.
Supervision of a step response
The adjusted set value is compared with the measured actual
value. If there is a difference between them and this difference
is greater than the tolerance, the supervision will initiate an error
after the settling time Tsr.Seegurebelow.

{0…99:99h} Default: 100ms
