HLR01.1N-48K0-N02R4-A-007-NNNN

The Bosch Rexroth Indramat HLR01.1N-48K0-N02R4-A-007-NNNN is a high-performance brake resistor in the HLR Brake Resistors series. Engineered for seamless integration with HCS02 and HCS03 servo drive controllers, it delivers a continuous output of 48 kW at a DC 700 V nominal bus voltage and features a resistance of 2.4 ohm. Its primary function is to absorb excess regenerative current during rapid deceleration of servo motors, protecting drive electronics and ensuring precise, controlled braking in automated systems.

Featuring a robust IP20 protection class housing, the HLR01.1N-48K0-N02R4-A-007-NNNN efficiently converts surplus electrical energy to heat. The resistor’s cement-coated casing acts as a non-conductive insulator, while strategically placed perforations facilitate rapid heat dissipation, maintaining thermal stability even under continuous loads. The precisely calibrated 2.4 ohm resistance aligns with the 48 kW power rating, ensuring current remains within permitted tolerance. Integration with a dedicated brake chopper enhances dynamic braking performance and extends the service life of the overall servo system.

Built to withstand industrial environments, the resistor’s IP20 enclosure prevents ingress of solids larger than 12.5 mm, boosting durability and operator safety. Fast heat transfer and stable operation at DC 700 V improve energy efficiency and reduce the risk of thermal overload. Compatibility with standard servo controllers simplifies installation and maintenance, while continuous power handling capabilities minimize downtime in high-duty applications. By deploying the HLR01.1N-48K0-N02R4-A-007-NNNN, manufacturers benefit from reliable energy absorption, extended controller longevity, and enhanced safety margins in diverse industrial automation processes.
