WEG: MVW3000


October 28, 2021

WEG introduces the new MVW3000 Medium Voltage Variable Speed Drive. With an easy-to-use HMI, which follows the same programming concept used by the LV line, the MVW3000 is perfect for a wide range of industrial applications that require speed variation, such as compressors, pumps, fans, conveyor belts and mills.

MVW3000 is a Voltage Source Inverter (VSI) based on the multi-level Cascaded H-Bridge (CHB) topology. The almost sinusoidal output waveforms produced by the drive allow the use of this VSD with new or existing synchronous and induction motors without demanding especial insulation.

User-friendly HMI

A door mounted 10-inch touch screen HMI offers great flexibility to the operator allowing easy access to user process data in real-time. Intuitive operation makes equipment parameterization, status reading and alarm/fault logging simple tasks.

It also supports several languages, multiple protection levels against unauthorized access, graphic and plotting functions.
