Product Description:

The HNF05.1A-500N-R1600-N-A5-NNNN is a three-phase mains filter manufactured by Bosch Rexroth Indramat and assigned to the HNF Mains Filters series. Installed ahead of regenerative servo or inverter drives, the unit blocks switching harmonics and returns a cleaner sine wave to the plant power bus, helping large automation cells meet electromagnetic compatibility requirements and protect upstream distribution equipment. It is intended for line-side installation in high-power motion systems where conducted noise from fast-switching drive electronics must be reduced before it spreads through the facility supply.

The device accepts input ranges from 3 × AC 380 V −15 % to 690 V +10 %, permitting operation across a wide range of industrial supply systems. Its continuous load capability reaches 1600 A, allowing one filter to serve multiple high-power converters without saturation. An enclosure rating of IP00 means the terminals are open and the filter must be mounted inside a touch-safe cabinet or enclosure. Electromagnetic performance is classified as C3 in accordance with DIN EN 61800-3, which suits industrial settings supplied by dedicated transformers. To shunt common-mode noise, the internal network includes line-to-ground capacitance totaling 500 nF, providing a low-impedance path for high-frequency displacement currents created during pulse-width-modulated drive operation.

Copper busbars limit series resistance to only 22 µΩ, so voltage drop and self-heating remain low even at full current. The filter is released as design version 1 on hardware platform 05, which identifies its product generation and mechanical format within the series. Bosch Rexroth specifies the assembly for regenerative devices only, so it is intended for drive systems that return braking energy to the supply during deceleration.
