Product Description:

The HNL01.1R-0590-C0065-A-480-NNNU is a three-phase mains choke used on the supply side of inverter and regenerative drive assemblies. It introduces controlled inductance that smooths input current, limits voltage spikes, and helps protect downstream rectifier sections from network disturbances. In production lines and test benches, it supports regenerative drive operation by reducing line-side stress and helping return energy to the grid with cleaner current behavior. This type of line reactor is suited to installations where stable supply conditions are important for dependable drive operation.

The choke is intended for mains at 3 × AC 400–480 V (-15/+10%) and grid frequencies of 50/60 Hz, so it can connect directly to common industrial feeders. Because the installation uses a regenerative power module, the choke must handle power flow in both directions, and an integral filter stage fitted with capacitors helps damp switching transients that appear during braking. Mechanical protection is provided by an IP10 enclosure rating, which helps prevent accidental contact with live conductors while still allowing natural airflow for cooling. It is typically mounted on a cabinet back panel so the iron core and winding assembly can release heat into the surrounding air without forced ventilation.

The choke is built to Design Version 1, which identifies the layout used for its terminals and mounting points. The unit is part of Series 01, and it is produced by Bosch Rexroth Indramat for the HNL Mains Chokes series. These identifiers place the component within an established product group for cabinet-mounted line reactors used with regenerative converter systems. The version and series codes indicate the product grouping used for this reactor and separate it from other configurations in the same platform.
