HLT01.1A-300K-N-010-NNNN

The Bosch Rexroth Indramat HLT01.1A-300K-N-010-NNNN braking unit from the prestigious HLT Braking Units series delivers robust performance in industrial DC bus applications. Designed to maintain the DC bus voltage by dissipating excessive energy as heat, this unit supports a DC-link voltage of 1000 VDC and offers a maximum continuous braking power of 300 kW with a cycle time of 240 seconds. Its primary function is to protect motion control systems from overvoltage during deceleration phases, ensuring reliable operation of machine tools, printing machines, textile equipment, and other servo-driven devices.

Built for demanding industrial environments, the HLT01.1A-300K-N-010-NNNN features an internal brake resistor arrangement that efficiently absorbs and dissipates energy during braking. The unit carries a protection rating of IP00 and must be mounted inside a control cabinet rated at least IP54 to shield it from dust and contaminants. Its climatic category of 3K3 and operation up to an altitude of 1000 m guarantee resilience to vibration and shocks. Installation requires a G1 mounting position with a minimum clearance of 100 mm at both top and bottom to ensure adequate airflow.

Designed for compatibility and durability, this braking unit operates reliably within an ambient temperature range of –10 to +40 °C, although efficiency gradually decreases beyond this span. The HLT01.1A-300K-N-010-NNNN conforms to industry-standard protection classes and vibration resistance criteria, making it suitable for integration into diverse automation systems. By safeguarding the DC bus against voltage spikes and offering consistent thermal performance, this unit enhances system longevity and operational safety in harsh industrial settings.
