HNF01.1A-M750-R0300-A-480-NNNN

The Bosch Rexroth Indramat HNF01.1A-M750-R0300-A-480-NNNN from the HNF Mains Filters series is a robust solution designed for industrial EMC compliance in the Industrial Area Per DIN EN. It features a nominal current of 300 and supports a Mains Connecting Voltage of AC 400-480v to protect regenerative drive units. This filter operates exclusively on Regenerative Units only supply systems and installs in a vertical orientation for streamlined cabinet integration. Built to maintain EMC limit values and provide reliable radio interference suppression, it is an ideal match for HMV series power supplies.

The filter’s enclosure carries an IP20 protection rating and is constructed from materials free of silicone and asbestos for long-term durability. Connection is achieved via shielded motor cables up to 75 m in length, ensuring trouble-free performance under Group 2, EN 61800-3, Class A specifications. An isolated transformer must be positioned between the mains and filter to suppress leakage currents from cable capacitance effectively. This design maintains compliance with 50/60Hz mains frequencies while preventing unwanted ground currents.

At the heart of the HNF01.1A are damping elements including chokes, precision resistors, and specialized interference-suppressing X and Y capacitors with self-healing ability to avoid short-circuits in the event of dielectric breakdown. The adaptive filter eliminates line disturbances around the 50/60Hz range, identified by its line code 1 classification. Complete with a one-year warranty, this mains filter delivers dependable EMC performance and protection for demanding automation environments.
