Note
Rated voltage
Refer to the maximum line voltage under "Connection voltages" in the technical data for
details of the rated voltage.
Note
Input voltage range that can be actually used
The dashed line represents a theoretical characteristic of the correction factor. The devices
have an undervoltage threshold, which leads to shutdown when the voltage drops below it.
Consequently, the input voltage range that is actually usable has a lower limit.
