At rated input voltage the device supplies the rated/maximum output currents. At input voltages above the rated input voltage the output
currents must be reduced accordingly at constant output power.
Figure 11: Derating curves input current BM4163
5)
This overload time is dependent on the motor current and of the heatsink temperature and is determined by the Ixt-monitoring of the
device.
6)
The mains current is reduced by at mains voltage of e.g. 480 V
AC
and permitted output power DC link (instead of 235 A
AC
the mains current is 195,8 A
AC
). When selecting the connected drives ensure that the output power of the DC link is not exceeded.

7)
This power output is only permitted for short periods of time (max. 60 s). This must be ensured by parametrization of the connected
drives.
