NORDAC FLEX Variable Frequency Drive - SK 205E

April 13, 2022
NORD DRIVESYSTEMS' NORDAC FLEX SK 205E is a feature-rich and versatile part of the NORDAC family of variable frequency drives.

The NORDAC FLEX Variable Frequency Drive - SK 205E series has been designed for use with conveyor systems in parcel distribution centers and warehouses, airport baggage transport systems, and other intralogistics applications. It features a power range of 0.33 to 30 HP, a compact design, and allows for high precision in synchronous and positioning applications via integrated POSICON control.


The precise and rapid current vector control ensures constant speeds with fluctuating loads. The SK 205E also offers maximum flexibility and energy efficiency.


It features a total of six digital and two analog interfaces, two encoder interfaces, and one integrated PLC for programming functions close to the drive.
