详细资料

The KE compact power supply modules generate the DC 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 voltage. This makes the device robust against supply fluctuations and disturbances irrespective of the particular supply voltage. The voltage boost in the DC enables a higher drive speed and output.
