HLL Bus Chokes
The HLL01.1N-10M0-S0100-A-007-05A0-NNNN is a passive line reactor manufactured by Bosch Rexroth Indramat for the HLL Bus Chokes series. The component is wired in the DC link of multi-axis drive systems where it smooths bus voltage, limits inrush current, and reduces harmonic energy returning to the supply. By improving current waveforms, the choke protects connected converters and lengthens their service life. It is typically positioned between the rectifier stage and the shared DC bus so that each inverter sees a stable link.
The choke is designed for a continuous load of 100 A, the benchmark current that can flow through its copper windings without exceeding the thermal class. Its core provides an inductance of 10 mH, establishing impedance that attenuates high-frequency ripple on the link. Short-duration events up to 250 A are tolerated, allowing the reactor to absorb fault-level energy until upstream protection operates. Losses released as heat equate to 300 W, so enclosure airflow must accommodate this steady dissipation. A housing classified at IP20 shields energized parts from finger contact yet offers no dust sealing, making cabinet mounting obligatory.
The reactor weighs 35 kg, a factor that influences panel load calculations and lifting procedures; proper support rails and fastening screws are advised. Permissible ambient conditions range from 0 °C up to 40 °C, keeping core losses and insulation stress within specified limits. To sustain the thermal profile discussed above, a minimum spacing of 80 mm around the choke is required so that convection and cabinet ventilation can remove the generated heat without affecting adjacent electronics.
