The KNK Mains Filters series from Bosch Rexroth Indramat comprises a range of integrated mains filter units developed for industrial drive systems that require both line filtering and mains choke functionality in a single assembly.
These filters are configured through the type code to match application requirements such as nominal current, EMC classification, cooling arrangement, and mounting style, making the series adaptable to different cabinet and machine designs. The series includes versions intended for three-phase AC mains systems in the 380 to 500 V range and also identifies configurations for regenerative applications. For installation flexibility, available variants include thermal-interface designs for cold-plate mounting as well as insulated mounting versions, alongside protected configurations rated up to IP65. Overall, the KNK line is structured as a drive-related power-conditioning series intended to support electromagnetic compatibility and electrical integration requirements in industrial automation environments.
