AC Adjustable Drives

Speedmaster® Micro Series compact inverters offer “big drive” features for adapting standard or premium efficiency three-phase motors to adjustable speed operation. Utilizing the latest microprocessor and advanced IGBT power conversion devices, these high performance controls program and read-out in plain English terms, eliminating the frustration and time involved in looking up confusing coded symbols. Complete, rugged steel enclosures for NEMA 1 (IP31) or NEMA 4/12 (IP65) service do not require additional enclosure protection as with many plastic-housed compact drives. Built-in thermal overload protection reduces additional costs. Heavy-duty wiring terminals, accessible via three conduit openings on the bottom of the housing, speed installation and cut costs. Available in single-phase and three-phase input models.
