Low Harmonic AC drives ACS800-U31/37 7.5 to 2800 hp Brochure
What is an Ultra-low Harmonic Drive? An Ultra-low Harmonic (ULH) drive has switching IGBT semiconductors in the supply side, instead of a conventional diode bridge. The drive is able to control the line current to sinusoidal waveform. Additionally, the line filter used in an ultra-low harmonic drive typically is designed to attenuate high-order voltage harmonics to reach very low total distortion of both current and voltage. Benefits Harmonic mitigation is built right into the ULH drive - -eliminating the need for additional expensive and space-consuming components like line reactors and transformers. This concept ensures the drive meets the IEEE 519-1992 standard at the input terminals of the drive. The harmonic performance is independent of supply imbalance, unlike 12- and 18-pulse solutions, and avoids any concern related to network resonances. Total harmonic distortion of the drive is typically 3.5 - 4.5% of the nominal rating and the drive always operates with power factor of 1. Features The ULH drive is available in both wall-mounted package and enclosed cabinet-built versions (depending on ratings and options selected). The power ratings of the wall-mounted type start from 7.5 hp heavy-duty rating and go up to 125 hp normal-duty rating. It is available in the NEMA 1 protection class. The cabinet-built drive is available in the power range of 40 hp up to 2,800 hp, and with NEMA 1, NEMA 1 filtered and NEMA 12 protection class - easily configured and ordered using our standard product catalogs. Where it can be used The ABB ACS800 ULH drive is the ideal solution for those drive installations where low harmonic content is desired or mandated. Its performance and simplicity of installation make it suitable to a wide range of industries and applications. Typical industries include HVAC, water and wastewater treatment, mining, metals, and pulp and paper mills. The most common applications for these drives are pumps, fans, compressors and conveyors.
