The MV1000 is a Medium Voltage (MV) AC drive that takes a generational leap in ease of application and installation.

With Yaskawa's Smart Harmonics™ Technology input isolation transformer and 9 level output for 4kV drives (17 level line-to-line), the biggest traditional issues with the application of MV drives all but disappear.

The MV1000 is a compact, all-in-one package including (optional) input switchgear, ideal for new or retrofit installations.
