Note
Inrush current
The device requires an inrush current of at least 6.5 A for 50 ms.
The peak value of the startup current depends on the input voltage and the impedance of the
24 V power source. Peak currents greater than 6.5 A are possible. This will not have a
negative impact on device functionality.
