Product Description:

The HNL01.2R-0300-C0180-A-480-NNNN mains choke is manufactured by Bosch Rexroth Indramat and belongs to the HNL Mains Chokes series. Positioned between the three-phase supply and regenerative drive modules, this component introduces controlled inductance that moderates current rise, reduces harmonic content, and shields power electronics from line-side transients in automated production cells. This arrangement helps stabilize the front end of the power path before energy reaches sensitive drive electronics. It is intended for systems that need smoother input behavior during normal operation and power return events.

The choke carries a degree of protection rated at IP10, so its enclosure blocks accidental contact with internal parts while remaining open for natural convection cooling. It connects to networks specified at 3 x AC 400-480 V with a permissible tolerance of -15% to +10%, allowing installation on common factory power systems without transformer adaptation. Frequency support spans 50/60 Hz, matching global power standards and supporting operation on either standard utility frequency. Because the supply system is regenerative, the choke must accommodate bidirectional energy flow and steady line interaction during returned power conditions. Additional filtering is handled by the integrated capacitive stage listed as with capacitors, which tunes the input impedance and helps suppress high-frequency noise.

The unit is Design version 2, indicating the second mechanical and electrical revision of the line. Within the internal numbering scheme, it is grouped under release 01. Its role is to smooth line interaction at the front end of the power system and help limit abrupt current changes during dynamic operation. It is suited for drive systems that need a dedicated input reactor to reduce line stress during changing load conditions.
