Product Description:

The HNL01.1R-0140-N0650-A-480-NNNN is a line-side inductive component produced by Bosch Rexroth Indramat for the HNL Mains Chokes series. Installed between the three-phase supply and an inverter, this mains choke attenuates differential current peaks, lowers harmonic distortion, and helps protect drive electronics from sudden voltage transients. By smoothing inrush and regenerative energy flow, it supports stable DC-link voltages and extends the service life of connected servo drives in industrial automation cells that use rapid braking or energy-feedback cycles. The compact iron core and copper winding are optimized for minimal stray inductance, making integration straightforward in multi-axis cabinets.

Electrical compatibility is centered on a mains connection of 3 × AC 400–480 V, and this voltage window matches common factory power grids. A tolerance band of -15/+10 % allows the choke to remain effective when supply levels sag during startup or rise during light loading. Operation spans standard industrial frequencies at 50/60 Hz, so no rewiring is needed when machines are moved between regions. The choke supports regenerative operation, so it can handle energy that flows back from the drive into the line without saturating its core. The enclosure rating of IP10 indicates finger-safe openings while relying on the surrounding cabinet for additional protection.

The unit is delivered as design version 1. It belongs to Series 01 within the HNL lineup, and the winding geometry, core stack, and terminal layout follow the initial release pattern used for this power class. The housing supports DIN-rail mounting or plate installation beside drive controllers, which suits standard cabinet layouts where the input filter, rectifier, and inverter stages are grouped in a compact section. During operation, the choke adds only minimal copper losses to the overall system while continuing to limit current peaks on the incoming line.
