About the new Micro-Speed Ultra Drives (MX/MV)
MX/MV Ultra series VFDs deliver advanced features, high performance, and unmatched reliability for the most demanding crane and hoist applications. Every Ultra drive is rated for 60°C ambient temperature and 300% overcurrent capacity, setting the industry standard for durability. Models up to 5 HP come standard with built-in heavy-duty regen resistors—ideal for travel motions, load-brake systems, and worm-gear hoists. Designed for tough environments and critical loads, these drives ensure smooth, safe, and efficient operation. Models available in all 3-phase voltages 208 – 600V and motor sizes 1 – 600 HP
