3-phase operation
below rated
supply voltage
The rated voltage is 3 x 400 V
At smaller supply voltages the output power of the device reduces.
1-phase operation
above rated
supply voltage
The rated voltage is 3 x 400 V
At supply voltages above the rated supply voltage, the output current is to be reduced at
constant output power, accordingly.

If the output current is multiplied with the output voltage, the output power of the device is pro-
vided.

In order to obtain the specified curve/surface, it is necessary, that the output current is reduced to
a value between 400 and 528 V.
