电源模块-KE系列

? Up to 50% less control cabinet space required ? Cost savings through possible integration of the control cabinet in the machine ? Solutions at optimal cost based on modular system design ? Application-related cooling technology

详细资料

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.
