Motor Control Solutions for Industrial and Material Handling Equipment
Micro-Speed® MX-Ultra® “H” Models (Load-Brake Hoist/Lifting Applications)
The Ultra™ VFD for hoisting/lifting applications (with a mechanical load brake). Ideal for advanced applications with motors 1-600 HP. Models available in all 3-phase voltages (208 – 600V).
Do you have a 1-20 HP load-brake hoist application and do not require any of the Ultra™ features? Press this button to view our CXRH series.
Available Models by Voltage (Open to View)
All hoisting models are pre-programmed for use in a lifting/vertical motion application (coast-to-stop, load-brake-controlled deceleration).

About the Micro-Speed® MX-Ultra® Models:
The Micro-Speed® MX-Ultra® hoisting models (models end with “H”) are our most advanced open-loop VFDs for horizontal and hoisting motions with an internal mechanical load brake or a self-locking worm gear design. 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.
