HNL05.1R-0135-N0327-N-A4-NNNW

The Bosch Rexroth Indramat HNL05.1R-0135-N0327-N-A4-NNNW is part of the HNL Mains Chokes series and is engineered to improve the performance of converters and regenerative supply units by boosting continuous DC bus power. Featuring a regenerative supply system and a nominal inductance of 327 µH, it significantly reduces harmonics in the line current to prevent perturbations in sensitive drive systems. With a three-phase AC input voltage of 400–480 V AC (–15/+10%) at 50/60 Hz and a rated current of 135 A, this mains choke is ideal for heavy industrial applications requiring robust power conditioning.

This current-compensated mains choke excels in delivering stable, clean power. The HNL05.1R model offers IP00 protection and operates reliably within an ambient temperature range of 0–40 °C and at installation altitudes up to 1000 meters. The device integrates seamlessly with Rexroth Indramat regenerative units, efficiently counteracting asymmetric currents on the mains connection. Its design ensures minimal losses while handling rated currents, and its inductance supports rapid transient suppression in dynamic load scenarios.

Durability and compatibility are at the core of this choke’s design. With no additional options required, it installs easily in standard control cabinets and adheres to Rexroth Indramat’s strict quality guidelines. Maintenance personnel must follow established safety protocols during commissioning. Suitable for sectors such as wood machining, metal forming, packaging, and general automation, the HNL05.1R-0135-N0327-N-A4-NNNW delivers enhanced efficiency and reduced downtime. Employing this mains choke in industrial installations ensures improved power quality, system longevity, and optimized performance in demanding environments.
