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.
