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. These enclosed drive solutions are available in both UL Type 12 / NEMA 12 enclosures, and UL Type 3R / NEMA 3R enclosures.
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
✓ Serviceable design, allowing fast & easy access to key components, including drive modules mounted on rail-system for safe, easy servicing
Easy to configure, ready to ship
Simple to quote and order thru local Control Techniques partners.
Factory stocked complete systems to support emergency shipments.
