VLT® Soft Starter MCD 600

Superior performance for fixed speed applications – Now available in an enclosure!

The VLT® MCD600 drive comes packed with functionality and possibilities to bring any machine control to a completely new level. The compact size is more flexible than ever to install, thanks to a wide variety of Ethernet and serial-based communication option cards, application-dedicated smart cards and support for eight languages. An integrated bypass ensures both extremely high efficiency and harmonic-free operation at full speed, reducing energy consumed and required cooling capacity. Ease of use is in focus with features such as the pump-clean function, PowerThrough operation, and calendar or run time-based scheduling. More extensive motor and starter protections ensure more uptime.
