Peak power
Comply with KCU peak power
The sum of the electric powers of all KSM/KMS of a drive line
should not exceed the indicated value P
DC_max
of the KCU drive
connection box.

Derating of Peak Power
As the length of the hybrid cable increases, the peak power available at the
cable end is reduced.
Peak power depending on the cable length
Due to occurring voltage drops, the effective length of the cable
influences the available peak power at KSM/KMS.
