Note
Inrush current
The inrush current of the device at an input voltage of 24 V amounts to at least 2 A for a
period of 25 ms.
The peak value of the inrush current depends on the input voltage and the impedance of the
24 V source; peak currents in excess of 2.0 A are possible. This will not have a negative
impact on device functionality.
