The R911307413 (HNF01.1A-M750-R0300-A-480-NNNN) is a mains filter from the HNF series, designed for vertical installation and operation with HMV power supply units for servo drives and motors lacking integrated filters. This line filter suppresses radio interference to ensure conformity with EMC requirements, specifically Group 2, EN 61800-3, Class A, supporting shielded motor cables up to 75 meters in single-cable configurations. It has a protection class of IP20 and is intended for use with an isolated transformer between the mains supply and filter. The device mitigates leakage currents, is constructed from silicone- and asbestos-free materials, and features scalable parameters for cable length, number of drives, and current. It consists of chokes, resistors, and self-healing X and Y capacitors, and adapts to 50/60 Hz mains frequencies with line code 1. The unit operates in industrial environments according to DIN EN EMC standards at AC 400-480V with a nominal current of 300 A and is for use with regenerative supply systems only.
