The performance specifications apply to the power supply component, but not to the device.
Note
Inrush current
The device needs an inrush current of at least 4 A for 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 4 A are possible. This will not have a negative
impact on device functionality.
