The rated power supply voltage is 3 x 400 V
The output currents must be reduced accordingly when operating with a power supply
voltage higher than 400 V.
Figure 23: Derating: Output current as a function of the power supply voltage
The device draws the rated/peak current at rated supply voltage. The input current must
be reduced if power supply voltage is higher than 400 V and the DC link output power re-
mains constant.
