About the Micro-Speed® MX-Ultra® Models:

The Micro-Speed® MX-Ultra® traverse models are our most advanced open-loop VFDs for travel motion applications. Built on the industry-proven platform of the Micro-Speed® Multi-Vector ® series. The MX-Ultra® runs the same advanced programming as the MV-Ultra® but without encoder feedback. Models are available in sizes ranging from 1-600 HP and with all 3-phase voltages.

Designed and manufactured in the United States for the crane, lifting, hoisting industries, and many other industrial applications. The Ultra® series is the latest brand of proven variable frequency drives from Power Electronics® International, Inc.® The line combines our highly reliable power sections and instant Gang-Set® programming of the Micro-Speed® line with the latest in easy-to-use web-based programming and communications.
