HNL01.1R-0540-C0094-A-480-NNNA

HNL01.1R-0540-C0094-A-480-NNNA, Bosch Rexroth Indramat, HNL Mains Chokes is engineered to enhance the performance of DC bus systems when paired with converters and feed supply units. This mains choke significantly reduces line current harmonics and prevents perturbations that could interfere with sensitive power electronics. It is explicitly intended for operation only when connected to a suitable discharging device and regeneration-capable supply. Strict adherence to safe commissioning practices is required, ensuring all connections are verified and the choke is fully isolated before touch or power-up.

Designed for robust industrial environments, the unit features an Additional Option: With Capacitors integration that shortens discharge intervals, achieving a full safe discharge in Discharge Time: 30 min. Its rugged enclosure meets Protection Type: IP10 standards and complies with EMC Standard: EN 61000-2-4 for interference immunity. The choke supports a Supply System: Regenerative topology, handling a Current Rating: 94 A continuous load with peak stability. Physical integration is straightforward: the compact footprint measures Dimensions: 340 x 385 x 229 mm (W x H x D) and weighs Weight: 65 kg, while heat losses are limited to Power Dissipation: 420 W. Input and output power terminals accept a Connection Cross-Section: AWG 2/0 (70 mm²) conductor, and the built-in Temperature Contact Cross-Section: AWG 14 (2.5 mm²) allows direct integration into monitoring circuits.

Integration of the HNL01.1R-0540-C0094-A-480-NNNA into converter cabinets yields immediate benefits in power density and system reliability. By smoothing DC bus voltage transitions and preventing semiconductor overloading during commutation events, it extends the service life of downstream drives. The mains choke’s plug-and-play form factor and standardized connections minimize installation time, making it ideal for high-power regeneration loops, machine tool feeds, and process automation systems.
