Input inrush current
An NTC limits the input inrush current after the input voltage is switched on. The inrush current surge depends on the input voltage and the ambient temperature. The output load has no influence on the value of the inrush current surge.
The charge current of the interference suppression capacitors during the first few microseconds after switching on is not taken into account.
