ABB ACS800-31 Wall-mounted low harmonic drives

ABB ACS800-31 Wall-mounted low harmonic drives

Easy low harmonic solution 

There is increasing concern among end users and power  companies about the harmful effects of harmonics. Harmonic  distortion may disturb or even damage sensitive equipment  connected in the same environment. Harmonics also cause  additional losses in the network. Harmonic standards are  thus becoming stricter and there is a growing demand for low  harmonic solutions. ABB’s low harmonic drives offer an easy low harmonic  solution incorporated in the drive. The solution to overcome  harmonic issues simply comes with the drive without the need  for additional filtering equipment or complicated multi-pulse  transformer arrangements.

Compact solution 

The ACS800-31 is low harmonic drive in a single, complete  wall-mounted package. It has an active supply unit and low harmonic line filter integrated in the drive resulting in less  cabling and installation work on site. This compact drive  package itself has extremely low line harmonics and thus  meets the strictest harmonic standards without any need for  additional filtering equipment. Due to the active supply unit it  always operates with power factor 1.

The power ratings of the ACS800-31 start from 5.5 kW heavy  duty rating and go up to 110 kW continuous load rating. It  is available in the IP21 protection degree. In line with the  ACS800 series, an extensive range of external options are  available including EMC filters and extension modules for  additional I/O.
