Product Description:
The HNF01.1A-P2K0-R1200-A-480-NNNN is a three-phase mains filter produced by Bosch Rexroth Indramat for the HNF Mains Filters series. Positioned between a regenerative drive and the facility mains, this component suppresses conducted interference and channels return energy so the upstream power network remains within industrial electromagnetic limits during motor braking and acceleration cycles. It is intended for cabinet-based drive systems that return braking energy to the supply line during normal operation. In multi-axis systems, it also helps limit electrical noise fed back onto shared plant power lines.
Its enclosure rating is IP20, indicating finger-safe access yet no sealing against liquids, which suits installation inside control cabinets. Electromagnetic compatibility is classified as C3, a category intended for industrial areas with dedicated distribution transformers and not for direct use near sensitive residential equipment. Nominal connection accepts 3 × AC 400–480 V lines, and the filter passes utility frequencies of 50/60 Hz without excessive impedance. This helps the mains supply remain stable while the connected inverter alternates between motoring and regeneration. The unit is intended for regenerative devices only, so the internal choke geometry and capacitor layout are tuned for bidirectional power flow rather than single-quadrant drives.
The unit uses Design Version 1, which confirms the mechanical dimensions and terminal positions for this hardware revision. Stable terminal placement also supports consistent wiring clearances when the filter is installed beside reactors, contactors, or regenerative power supply modules. The internal code 01 identifies its place in the series and helps match it with similarly coded line reactors or EMC options. The permissible mains variation of −15 % to +10 % around the stated 400–480 V range is the voltage window in which the filter maintains rated insertion loss without core saturation or thermal derating. These values are useful when the incoming supply is not perfectly nominal but still remains within the accepted operating range.
