The HLB01.1C-01K0-N06R0-A-007-NNNN from Bosch Rexroth Indramat is part of the HLB Resistor Brake Units series and serves as an essential component for controlled deceleration and energy recovery in servo drive systems. Featuring an Input Voltage range of 254...750 Vdc and a Nominal Power rating of 1 kW, this brake unit efficiently dissipates regenerative energy during braking. Its primary function is to divert kinetic energy from the motor back into the system, reducing wear on mechanical brakes and enhancing operational safety in industrial automation applications.
This brake unit offers robust technical performance, including a Braking Resistor Peak Power of 100 kW and a DC Nominal Bus Voltage of 700 V. The Resistance is precisely set at 6 Ohm to ensure consistent energy dissipation, while the Maximum Inrush Current at 24 V Supply is limited to 3 A to protect the control electronics. It operates with a Pulse Width of 50 ms, supporting rapid bursts of braking demand, and consumes 14 W under rated conditions. The unit’s protection rating of IP20 safeguards internal components against solid objects, and its total weight of 5.8 kg contributes to straightforward handling and installation.
Designed for seamless integration into industrial drives, the HLB01.1C-01K0-N06R0-A-007-NNNN also incorporates a DC bus short-circuit function for emergency braking in the event of power failure. Its compact dimensions and moderate weight facilitate retrofits and modular installations without significant space penalties. With its high peak power capacity and precise control over regenerative currents, this resistor brake unit maximizes energy efficiency, minimizes waste heat, and extends the service life of both motors and mechanical brakes. Reliable, durable, and engineered to meet the rigorous demands of modern automation, it offers clear benefits in terms of performance, safety, and cost savings in industrial applications.
