Air-cooled medium-voltage drive with 6-step regenerative (4-quadrant) line-side behaviour.
Air-cooled Perfect Harmony GH180 variant with a 6-step regenerative front end, giving four-quadrant operation for regenerative and braking duty. Functionally identical to the 2Q air-cooled design and
This product line is built to your application: the configuration (size, ratio, brake, encoder, fieldbus, mounting) is defined together with our technical team, so there is no fixed article number to pick from a shelf. Tell us your duty point and we come back with a configured proposal and a price.
