HNL01.1E-0571-N0050-A-500-NPNN, Bosch Rexroth Indramat, HNL Mains Chokes. The HNL01.1E-0571-N0050-A-500-NPNN mains choke from Bosch Rexroth Indramat is part of the HNL Mains Chokes series and is engineered to enhance DC bus performance by smoothing line currents and attenuating high-order harmonics. Designed for seamless integration with converters and supply units, this choke achieves stable continuous power delivery while preventing disruptive feedback into upstream circuitry. The robust design employs environmentally considerate materials that are fully recyclable, reinforcing Rexroth Indramat's commitment to sustainability and long-term operational efficiency. A precisely engineered core and winding assembly maintain electromagnetic compatibility while minimising size and weight in compact installations.
The choke supports a Continuous Current rating of 50 A and reliably dissipates up to 50 W of power under normal load conditions. Its Inductance is specified at 3 × 571 µH, ensuring effective smoothing of pulsating DC currents. Cooling is provided by Natural Convection, eliminating the need for auxiliary fans and reducing maintenance overhead. The device incorporates a Supply System compatibility with Rectifier configurations and meets an IP10 Protection Type to guard against ingress of large solid particulates. No additional accessories are required, as denoted by the Additional Option: None entry. Operators should note the generation of an electromagnetic field during operation and observe safety clearances for sensitive equipment.
Installation and serviceability are streamlined by a compact, bolt-on housing that accepts standard mounting interfaces and accommodates unrestricted air flow. The choke is certified for global shipment with a Warranty Period of one year, underscoring its reliability and Bosch Rexroth Indramat's confidence in performance. Ideal for integration into industrial power systems, the HNL01.1E-0571-N0050-A-500-NPNN delivers consistent harmonic mitigation and dependable operation in demanding manufacturing and automation applications.
