The power specifications apply to the power supply component not to the device.
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 de
vice functionality.
