Inrush current
The device needs an inrush current of at least 6.5 A for 15 ms.
The peak value of the starting current depends on the input voltage and the impedance of
the 24 V DC power supply. Peak currents greater than 6.5 A are possible. This will not have
a negative impact on device functionality.
