Product Description:
The HNF01.1A-M900-R0065-A-480-NNNN is a three-phase mains filter produced by Bosch Rexroth Indramat within the HNF Mains Filters series. This cabinet-mounted unit is installed between the plant power bus and the drive package to suppress conducted noise, return energy from regenerative drives safely to the grid, and help the entire axis group meet industrial electromagnetic compatibility targets during continuous machine operation. By attenuating high-frequency currents, it supports stable operation of multiple servo inverters on a common supply, helps prevent disturbances from propagating to upstream equipment, and reduces unwanted electrical noise on shared incoming power lines.
The filter connects to factory power networks rated at 3 × AC 400–480 V –15 % to +10 % at 50/60 Hz, which allows operation on common low-voltage industrial systems. Its housing carries an ingress protection level of IP20, so live parts are finger-safe, but the device still requires installation inside a control cabinet for external protection. The cabinet provides the required shielding against surrounding conditions and keeps the filter away from direct exposure to dust or moisture. Emitted and conducted interference is limited to the C3 in accordance with DIN EN 61800-3 category, which is suitable for equipment used in industrial facilities that are not directly connected to public mains. The internal topology is sized for regenerative devices only, so it can handle energy fed back from braking drives without overstressing the line.
Within those limits, the filter is dimensioned for installations that include up to 15 axes of servo or spindle control, and its output stages support a combined motor cable reach of 900 m without exceeding the specified attenuation curve across the connected drive group. This allowance is useful in larger machine sections where several cabinets or drive branches share the same filtered mains connection. The mechanical and electrical layout corresponds to Design Version 1, and the unit is part of series 01, which identifies the revision used for this model. It integrates with regenerative power supply modules in multi-axis systems, allowing recovered braking energy to return to the grid while keeping cabinet wiring straightforward.
