R911306580
The R911306580 (HNL01.1E-0400-N0051-A-480-NNNN) mains choke is a product by Bosch Rexroth Indramat. Designed for use with components that lack regeneration to the supply mains, this HNL-range choke can be paired with supply units and converters. Structured to dampen high current peaks by up to 40%, it also includes a built-in feed supply system. Its dimensions are 180 x 112 x 225mm. It's designed for positioning in line with AC line power at the input point.
This mains choke enhances operational efficiency by reducing effective mains current. Specifically, it restricts the recharging currents in large drives and drive systems, and it's useful in suppression circuits. This three-phase device has a voltage rating of 400VAC to 480VAC with a tolerance of -15%/10% and a current rating of 51A. Importantly, the choke must be installed by trained staff, due to its function of interfering minimization between the mains supply and other devices. The unit exhibits a nominal inductance of 400µH, contains one temperature contact, and no additional options are supported. The unit comes with a type plate for relevant service information and is packaged securely to minimize transit damage. Proper installation can limit converter-generated feedback and boost overall functionality.
