Módulos de alimentação compactos KE

The KE compact supply modules generate the DC bus voltage for the connected
inverters and are available in the following versions:

KEN:
Not line regenerative supply module
KE:
Line regenerative supply module
KES:
Sinusoidal line regenerative supply module
The KES product range featuring sinusoidal supply and line regeneration generates a
regulated DC bus voltage. The products stand out from various other systems due
to their robust design. Higher drive speeds and performance can be achieved through
the voltage boost in the DC link.

Benefits:

• High power density
• High efficiency

• Sustainability through line regeneration
• KES: Distortion of the main
• KES: Limits of harmonic currents

Features:
• Power ratings up to 120 kW
• Cooling in cold plate technology
• Line regenerative braking optional
• Protective functions
        - Overtemperature
        - Power failure
        - Input current
        - Short circuit protected
        - DC bus overcurrent
        - Main contactor control
