Input Inrush Current

7 Input Inrush Current
An active inrush limitation circuit (NTCs, which are bypassed by a relay contact) limits the input
inrush current after turn-on of the input voltage.
The charging current into EMI suppression capacitors is disregarded in the first microseconds
after switch-on.
