TMdrive-Guardian outdoor enclosure for the company’s TMdrive-MVe2 medium-voltage variable-frequency drive (VFD) eliminates the need to house the drive in a temperature-controlled, industrial-control building or E-house, offering the potential to save thousands of dollars and easing engineering, procurement, construction and maintenance. TMdrive-MVe2 eliminates the challenges associated with aging VFD designs, such as low efficiency, fixed input power factor, and high output harmonics.
