Product Description:

The HNF05.1E-500N-R1600-N-A5-NNNN is a three-phase mains filter produced by Bosch Rexroth Indramat within the HNF Mains Filters series. In multi-axis drive systems, it sits between the facility supply and an inverter stack, where it attenuates high-frequency interference and limits the return of regenerative energy to the grid. By conditioning the power lines, the component helps connected drive controllers meet electromagnetic compatibility requirements and reduces the effect of switching transients on upstream equipment.

It is rated for a nominal line current of 1600 A, allowing it to be installed ahead of large regenerative drives without saturating its magnetic elements. The operating voltage range is 3 x AC 380 V to 690 V, which matches common industrial distribution networks in both 400 V and 600 V classes. The permissible input deviation is -15% / +10%, so the filter continues to operate during moderate brownouts or overvoltage conditions on the plant bus. With a leakage capacitance of 500 nF, the unit redirects high-frequency common-mode currents back to the source while keeping touch current within expected safety limits. Its enclosure classification is IP00, which means the assembly must be mounted inside a control cabinet where accidental contact and exposure to dripping liquids are prevented.

The filter uses design version 1 and belongs to product family code 05. It is specified for use with the HMU05 regenerative inverter, which places it in applications where recovered braking energy is handled through a regenerative power path rather than by dissipation. The supply system designation for regenerative devices only states that intended operating mode clearly. This unit functions as a mains filter, so it serves as a passive EMC stage between the incoming supply and the connected drive hardware.
