Product Description:

The HNF05.1E-500N-R0150-N-A5-NNNN mains filter is built by Bosch Rexroth Indramat and belongs to the HNF Mains Filters series. The HNF05.1E-500N-R0150-N-A5-NNNN is installed between the plant supply and the DC bus of drive packages, where it limits high-frequency emission and reduces harmonic feedback. By conditioning the power line, it helps regenerative servo inverters return recovered energy to the grid without exceeding electromagnetic compatibility limits. This placement allows the filter to act on the incoming supply before power reaches the connected inverter sections in a multi-axis cabinet.

At the electrical interface, this filter is rated for a nominal current of 150 A, allowing it to pass the continuous load drawn by medium-power drive groups without saturation. Its input accepts 3 x AC 380 V -15% to 690 V +10%, so it can be connected to a broad range of regional three-phase supplies. A leakage capacitance of 500 nF results in displacement current toward protective earth and should be considered when sizing residual-current monitors. Because the unit carries a protection rating of IP00, it has no inherent touch-safe enclosure and must be mounted inside a grounded control panel. Mechanical and thermal compatibility with the HMU05 inverter family supports installation because the filter terminals align with the rectifier input and the impedance curve matches the drive's regenerative profile.

This model is specified for regenerative devices only, so it should not be wired ahead of non-regenerative converters that cannot return energy to the mains. The unit is assigned to series 05, which groups filters with the same dimensions and impedance characteristics. It is released as design version 1. These identifiers indicate the product generation used for this filter and distinguish it from other models in the HNF range.
