HLR01.1N-66K0-N04R2-B-010-NNNN

The HLR01.1N-66K0-N04R2-B-010-NNNN, Bosch Rexroth Indramat, HLR Brake Resistors delivers industry-leading performance in servo drive energy management. Engineered specifically for integration with the HSC02 and HSC03 servo drive series, this brake resistor converts regenerated kinetic energy into heat with high efficiency. Its robust construction meets IP20 protection standards, ensuring reliable operation in typical machine tool environments. The unit’s compact design mounts directly above the drive inverter to take advantage of the converter’s exhaust airflow for passive cooling and space optimization.

The brake resistor offers a Continuous Output of 66 kW at a nominal bus voltage of DC 700 V and an ohmic Resistance of 4.2 ohm, providing high load capacity for demanding applications. It can absorb up to 5000 kW of peak regenerative power bursts, safeguarding drives against overvoltage trips. The component operates over an ambient temperature range of 0 … 40 °C without derating and features a Minimum Cycle Time of 120 seconds for repeated braking sequences. Installation clearances follow manufacturer guidelines to prevent heat damage to surrounding materials, and the passive cooling method eliminates moving parts, reducing maintenance.

Seamless integration with Bosch Rexroth Indramat’s drive controllers via an external brake chopper simplifies configuration and ensures precise braking control. Industrial operators benefit from enhanced system uptime thanks to the resistor’s robust design, high thermal endurance, and protection class compliance. Globally supported by Wake Industrial with a one-year warranty, the HLR01.1N-66K0-N04R2-B-010-NNNN excels in applications from high-speed conveyors and electric rail vehicles to hybrid automotive test benches, where dependable energy dissipation is critical.
