Mass produced low harmonic drive eliminates disturbances

January 5, 2010
The low harmonic drive attack distortion at the source by performing real time analysis and actively imposing currents, as needed, to restore and ensure the highest possible quality sine waves from the power supply grid. Additionally, they feature a modular design meaning that most elements are produced in large scale for cost effective production. They can be individually configured according to the customer’s specific needs. The drives have features such as high energy efficiency, backchannel cooling and user-friendly operation and are available in the power range 132 – 630 kW high overload, 160 - 710 kW normal overload, and voltage range of 380 – 480 VAC, 50 – 60 Hz. They meet the IEEE519 recommendation, are available in an IP 21/NEMA1 or IP 54 (hybrid) enclosure, are UL, cUL and Ctick listed, and carry the CE mark. They are also well suited for: tough harmonics recommendations/standards; installations that are generator-powered, or that have generator back-up power; soft power grids; and grids with limited excess power capacity.
