Micro-Speed® MX-Ultra™ (Hoisting Models)

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).

<<< Back to all versions of this product

Micro-Speed® Ultra™ "a2" frame size is shown. All Ultra™ Series VFDs are rated for up to 60°C and include our most advanced programming and connectivity features!

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.
