Product Description:
The HNF01.2D-F240-E0051-A-480-NNNN is a mains-side electromagnetic compatibility filter produced by Bosch Rexroth Indramat as part of the HNF Mains Filters series. Installed between the plant supply and an inverter cluster, it attenuates conducted noise that would otherwise propagate onto facility wiring. The unit is intended for multi-axis motion platforms in packaging machines, transfer lines, and similar installations where a single cabinet houses several servo drives. By limiting high-frequency return currents, it protects upstream equipment and helps the machine meet harmonic disturbance limits in industrial automation cells.
It accepts 3-phase 400–480 V AC mains with a tolerance of -15% to +10% and operates at 50 or 60 Hz, matching common factory distribution systems. The unit is intended for up to 6 axes and a combined motor cable length of 240 m, which sets the supported downstream load while maintaining rated insertion loss. The product is design version 2, with updated core material and terminal spacing to improve heat dissipation. It meets EMC limit class C2 – DIN EN 61800-3 across an extended frequency range through an internal L-C topology that reduces differential-mode and common-mode interference. Its IP20 enclosure is finger-safe but requires installation inside a control cabinet.
The filter is designed to keep core saturation low even when the supply network is unbalanced. It occupies the 01 platform, so its mounting points and busbar spacing match companion drive stacks in the same cabinet. Because it is specified for feeding devices only, power flows in one direction and braking energy must be handled by separate resistors rather than by the filter. This separates line filtering from regenerative energy handling and keeps each function in its proper part of the system.
