Product Description:
The HNF01.2D-M900-E0125-A-480-NNNN is a three-phase mains filter from Bosch Rexroth Indramat in the HNF Mains Filters series. It is installed between the plant supply and multiple drive controllers to reduce conducted electromagnetic noise before it reaches the rest of the system. This placement helps prevent switching noise from the drive group from returning directly to the plant mains. By lowering interference on the incoming lines, it helps connected drives operate more cleanly in cabinets that contain several power devices. The unit is intended for control cabinets where long motor cables and high axis counts can increase noise on the supply network.
The filter accepts a supply of 3 × AC 400–480 V (-15%/+10%), 50/60 Hz, which matches common low-voltage industrial mains while allowing normal line variation. A protection rating of IP20 means the terminals are finger-safe, but the unit still requires installation in an enclosed panel to keep dust and liquids away from energized parts. Compliance with C2 - DIN EN 61800-3 indicates that the filter is intended to limit conducted emissions in industrial environments connected to shared power systems. In practice, this supports cabinet installations that must control line-side interference without exposing live connections during normal access. The unit is built in Design version 2, which identifies this release of the internal filter layout.
The filter can support up to 15 axes on one bus, and its inductance allows combined motor cable lengths of up to 900 m. It is intended for feeding devices only, so it should not be used with general-purpose loads or unrelated cabinet equipment. Using one filter for several axes centralizes line-side interference suppression at the cabinet supply entry instead of at each individual drive. The unit is part of Series 01 in the HNF family, which marks the first functional generation of this design. That arrangement suits multi-axis installations where several drive power sections share a common supply path.
