For many drive users, designing and building a high power drive enclosure requires extensive in house engineering expertise and time that they do not have.

Control Techniques' Unidrive DFS (Drive Free Standing) is a pre-assembled, ready to install drive enclosure system designed for use in high power applications to deliver optimum motor control and energy efficiency. 

Save engineering cost, resource, and time through easy configuration of quality packaged drive systems that are highly adaptable for stand-alone applications, or ready to integrate into a broader system suite. 

Unidrive DFS Highlights:

No extra engineering required!

✓ Easy to integrate Rittal enclosures that include as standard: NEMA12 roof-vented, circuit breaker (35kA MCCB), fuses (UL), line & sharing chokes, and cabling (UL).
✓ Broad suite of option packages to meet various demanding applications & environments
✓ Increased safety against arc-flash with provisioning for isolator sequestering
✓ Compact design minimizes footprint
