HNF Series

The HNF01 Mains Filter Series is part of the Mains Filters Series that are manufactured by Bosch Rexroth. These filters are used for reducing radio interference and pollution of the mains and are tailored to the control units that they work with and can suppress leakage currents which are caused by cable capacitance. When using a Mains Filter it is important that it is used with an isolated transformer which is positioned between the mains and mains filter. The HNF01 Mains Filter Series is used to suppress interference of three-phase drive controllers with voltages up to 480V, and is also used for drive systems that have high numbers of axes and longer motor cables.
