3–Phase All Pole Sinusoidal Filter, 3AFSAP400 Series
All pole sine filters achieve excellent EMC properties, since both conducted and radiated disturbances are minimised. The usage is recommended for filtering the drives of for example elevators, fans, pumps and compressors, which are located in sensitive environments. This includes medical facilities, measuring laboratories, IT or residential areas.
Another field of application is found in spatially extended drive systems such as tunnels, wind power plants, mines where often long screened cable must be installed. Therefore the use of an all-pole sine filter eliminates the cost and complexity of installing screened cables.
