The electronic current limitation function is typically

used from 1.8 x I

This means that, typically, 1.8 times the nominal

current* is flowing in the case of all overload conditions

that lead to a shutdown (regardless of the power supply

and load circuit resistance). The shutdown time ranges

from 100 ms to 3 s depending on the multiple of the

nominal current, or in the event of a short circuit (I
