When it just needs to be kept simple: MOVI4R‑U® The basic inverter is the ideal product for basic applications in drive technology.
Not just for the control cabinet: it can also be used in other areas with an IP54 degree of protection

Our MOVI4R-U ® frequency inverters provide the precise functionality that you need to reliably control the speed of asynchronous motors. Not less - but with considerable added value!
The modular design of the MOVI4R-U ® basic inverter, for example, is ideal for quick unit replacement. And the intuitive MOVI4R-U ® operating concept enables impressively short startup times.
