HLL05.1F-04M0-S0603-N-D7-01U2-NNNN

The Bosch Rexroth Indramat HLL05.1F-04M0-S0603-N-D7-01U2-NNNN from the HLL Bus Chokes series is engineered for demanding industrial environments, offering 4 mH inductance and a 603 A continuous current capacity to stabilize high-power DC bus applications. Rated for a 750 V nominal DC bus voltage, this bus choke effectively regulates current flow and suppresses voltage fluctuations, ensuring reliable operation in power converters and drives. Its primary function is to maintain system stability by attenuating high-frequency interference and smoothing DC current in automated machinery setups.

In terms of technical specifications, this model delivers a rated power of 5.5 kW and achieves an efficiency of 97% across an input voltage range of 380-480 VAC. It operates within a frequency range of 0-60 Hz and incorporates an allowed leakage capacitance of 1.2 μF to ensure controlled energy discharge during transient events. The component’s protection class of IP00 designates it for installation within guarded electrical cabinets, while its robust construction supports consistent performance under sustained loads. Weighing 98 kg, the HLL05.1F-04M0-S0603-N-D7-01U2-NNNN combines high thermal resilience and mechanical stability for continuous operation.

Additional features include an ambient operating temperature rating up to 40 °C and a design that prohibits parallel connections on both the input and output sides to prevent inefficiencies or inadvertent current imbalances. The choke’s compact yet heavy-duty design minimizes footprint while delivering superior durability and longevity in industrial automation systems. Certified for industrial power applications, it ensures efficient thermal management and system compatibility in power converter assemblies. By integrating this DC bus choke into high-power drives, users benefit from enhanced stability, reduced electrical noise, and improved overall efficiency in complex automation processes.
