The QT20 series shall not be used with a DC-input voltage without consulting PULS.

Check QTD20.241 for DC-input voltage. (special version for intermediate bus systems, drive systems)

An active inrush limitation circuitry limits the input inrush current after turn-on of the input voltage and after short

input voltage interruptions.

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