Hold-up Time and Output Response
When the input voltage is switched off, the output voltage
will remain high for a certain hold-up time
th before the out-
put voltage falls below 0.95
Uo nom.
The behavior of the outputs is similar with either the input
voltage applied or the inhibit switched low.
An output voltage overshoot will not occur when the module
is turned on or off.

Conditions: R input not used. For multiple output modules the figures indicated in the table above relate to the output which
reacts slowest. All outputs are resistively loaded. Variation of the input voltage within
Ui min...Ui max does not influence the
values considerably.
