The KE compact power supply modules generate the DC link voltage for the connected inverters and are available in the following variants:
KEN:
Power supply (no regeneration)
KE:
Block-commutated power supply and regeneration
KES:
Sine-wave power supply and regeneration
The KES product series with sine-wave power supply and regeneration produces a regulated DC link voltage. This makes the device robust against supply fluctuations and disturbances irrespective of the particular supply voltage. The voltage boost in the DC link enables a higher drive speed and output.
