All parameters are specified at 24V, 3.8A, 230Vac, 25°C ambient and after a 5 minutes run-in time unless otherwise noted.

DC-Input
Do not operate this device with DC-input voltage.
5.
Input Inrush Current
A NTC limits the input inrush current after turn-on of the input voltage. The inrush current is input voltage and ambient
temperature dependent. The output load has no impact on the inrush current value.
The charging current into EMI suppression capacitors is disregarded in the first microseconds after switch-on.
