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.

Derating curves input current BM4145
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 125 A
AC
the mains current is 104,2 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.

Only valid for cooling variant S.

The cooling air requirement corresponds is at least to that of a free-blowing device. Free-blowing means, that the air inlet and the air
outlet takes place unrestricted. With the mounting of the device into a control cabinet it therefore can be necessary to use additional
fans, so that the necessary cooling air requirement is covered. If the necessary cooling air requirement of the power heat sink is not
provided, then the output power of the device has to be reduced.
