At rated input supply voltage the device supplies the rated- / maximum output currents. At input voltages above the rated supply voltage
the output currents at constant output power have to be reduced, accordingly.

The peak output current is supplied for the maximum peak current period for the motor at the first acceleration (cold power unit). The in
fact possible overload time is dependent on the preload of the device and on the heat sink temperature, it is determined by the overload
monitoring of the device.
