Product Description:

The HNL05.1R-0100-N0190-N-A5-NNNN is a line reactor manufactured by Bosch Rexroth Indramat and supplied within the HNL Mains Chokes series. Installed between the three-phase utility feed and regenerative power modules, the choke increases source impedance to attenuate high-frequency harmonics and limit inrush currents that can stress drive electronics. It is typically placed ahead of the regenerative power section so the drive system draws current from the supply more smoothly during dynamic load changes. In industrial automation, the unit is used to improve voltage quality and protect converters that return energy to the grid during braking cycles.

Its inductive rating of 100 µH provides the smoothing reactance that filters differential-mode current spikes on each phase conductor. The choke is designed for supply lines from 3 x AC 525 V -15%...690 V +10%, allowing use in industrial cabinets connected to a broad range of plant power systems. When loaded to its nominal throughput of 190 A, copper and core heating must be considered because the enclosure has an IP00 protection rating and relies on surrounding switchgear ventilation. With a mass of 25 kg, the unit requires solid mechanical support inside the cabinet. Continuous conduction produces about 180 W of power loss, so adjacent components need enough airflow and spacing to prevent heat buildup.

The unit is design version 1 and is intended for regenerative supply systems, so it can handle bidirectional energy flow when converters return power to the mains. That operating mode is important in drive systems where braking energy is fed back instead of being dissipated as heat. Liquid cooling is unnecessary because the specified water power loss is 0 W. No additional options are fitted, so the choke remains in its standard configuration and can be integrated without extra cooling hardware.
