Product Description:
The HNF01.2D-M900-E0051-A-480-NNNN is a mains filter produced by Bosch Rexroth Indramat for the HNF Mains Filters series. It is installed between an industrial three-phase supply and drive packages to attenuate conducted noise and keep high-frequency switching currents from returning to the plant network. By limiting electromagnetic interference, the filter allows multiple servo axes to share one feeder without creating disturbances that can affect nearby automation equipment. This arrangement supports cleaner power distribution in cabinets that combine several drives, control modules, and connected motion axes.
The housing carries a protection rating of IP20, indicating finger-safe access while relying on the control cabinet for the surrounding enclosure. Its input accepts 400–480 V AC three-phase power with a -15%/+10% tolerance, and the design supports standard line frequencies of 50/60 Hz. Compliance with C2 - DIN EN 61800-3 permits installation in industrial locations where suppression of conducted interference is important for stable operation of nearby equipment. The power stage is sized so a single unit can service up to 15 axes, which helps centralize line filtering in multi-drive cabinets and reduces the need for separate filter hardware on each axis.
A permissible cumulative motor-cable length of 900 m allows the drives to be distributed along conveyors or gantry sections without relocating the line filter. Mechanical layout follows design revision 2, matching the mounting pattern and internal arrangement used for this version of the product. Because the supply system is intended for feeding devices only, the filter is not intended for regenerative power flow back to the mains and must be used with front-end equipment that handles returned braking energy. The electromagnetic behavior of the unit follows the design approach used by Bosch Rexroth Indramat for modular drive systems in industrial automation.
