The Bosch Rexroth Indramat HLL01.1A-063U-N0861-C-008-1260-NNNN motor filter belongs to the HLL Bus Chokes series and is engineered by Bosch Rexroth Indramat for demanding industrial automation tasks. Featuring a nominal inductance of 63 μH, a continuous current rating of 861 A, and a nominal voltage of 3 AC 400 V, this robust component provides critical suppression of electromagnetic interference on DC 24 V drive buses. Its primary function is to filter and smooth high-current pulses, ensuring stable power delivery and protecting sensitive motor drives from voltage spikes and harmonic distortion.
This bus choke offers precise technical performance tailored to high-power applications. The module has a switching frequency of 4 kHz to accommodate rapid current transitions and minimize reactive losses. Rated for a maximum power loss of 625 W, it delivers efficient energy handling while maintaining thermal stability. The choke’s rugged housing measures 890 mm in width, 240 mm in height, and 377 mm in depth, and weighs 105 kg, reflecting its heavy-duty construction. An integrated current reduction feature at output frequencies below 4 Hz helps prevent overheating under low-speed conditions, extending component life and ensuring consistent performance under varying load demands.
Built for seamless integration with IndraDrive systems, the HLL01.1A-063U-N0861-C-008-1260-NNNN excels in compatibility and durability. Its robust design withstands harsh industrial environments and high-temperature operation, delivering reliable filtering with minimal maintenance requirements. The combination of high current capacity, low insertion loss, and advanced saturation resistance makes this choke an efficient solution for large-scale motor installations. In industrial applications, users benefit from improved power quality, enhanced drive reliability, and reduced downtime, resulting in optimized productivity and long-term cost savings.
