HLL05.1W-04M0-S0303-N-D7-01U2-NNNN

HLL05.1W-04M0-S0303-N-D7-01U2-NNNN, manufactured by Bosch Rexroth Indramat, is part of the HLL Bus Chokes series. This DC Bus Choke is engineered to suppress harmonic distortion and smooth DC voltage levels in industrial automation systems. It offers an inductance of 0.303 mH and a rated voltage of 400V, ensuring stable power delivery under varying load conditions. With a nominal current capacity of 30.3 A, it supports high-performance drives, inverters, and converter applications.

The choke measures 100 x 200 x 300 mm and weighs only 2.9 kg, making it suitable for compact cabinets and control panels. Housed in an IP 20 enclosure, it withstands indoor industrial environments across a temperature range of 0°C to 40°C and at altitudes below 1000 m. A natural convection cooling scheme limits power loss to 50 W without auxiliary fans, while compatibility with cable diameters from 6 to 16 mm² simplifies field wiring. Designed for DC applications, the device maintains performance without derating throughout its operational range.

Engineers will appreciate the ease of integrating this choke into existing DC bus networks, where its low-loss characteristics and robust protection class enhance system reliability. The HLL05.1W-04M0-S0303-N-D7-01U2-NNNN supports consistent voltage smoothing, reducing downtime and extending the life of drives and power electronics. Ideal for industrial automation, robotics, and material handling installations, it delivers long-term operational stability and simplified maintenance.
