General information

The tables below provide an overview of the power loss of all components during rated
operation. The characteristic values apply for the following conditions:
● DC link voltage 700 V
● Pulse frequency of the Motor Modules 4 kHz
● Operating components at their rated power
The total losses of the relevant power unit are calculated from the power loss and the
corresponding electronics loss of the power unit.
