Input inrush current

Active inrush current limitation (NTCs that are bridged by a MOSFET) limits the inrush current after the input voltage is switched on.

The charging current into EMI suppression capacitors is disregarded in the first microseconds after switch-on.

Input inrush current	Max.	8A	At +25°C ambient, cold start
	Max.	10A	At +40°C ambient, cold start
	Typ.	6A_peak	At +25°C ambient, cold start
	Typ.	8A_peak	At +40°C ambient, cold start
Inrush energy	Max.	1A²s	At +40°C ambient, cold start
