HLR01.1N-15K0-N08R1-A-007-NNNN

HLR01.1N-15K0-N08R1-A-007-NNNN, Bosch Rexroth Indramat, HLR Brake Resistors series brake resistor delivers robust performance for modern drive systems. Designed to absorb regenerated energy up to 1584 kWs, it sustains a maximum dissipation of 74 kW and operates continuously at 15 kW for brake power duration. The flameproof resistor elements are housed in an IP20 enclosure to guard against solid contaminants, while on-time duty capability of 21 seconds ensures safe handling of short-term peaks. Integrated mounting above the converter and a natural convection cooling scheme provide maintenance-free operation in demanding environments.

Technical specifications emphasize precise control: a braking resistance of 9.1 Ohm matches DC link voltages of 700 V DC, and a 3 AWG copper wire with PVC insulation connects directly to the converter. The device dissipates 15 kW continuously for up to 120 s without derating, and absorbs peak kinetic energy with 21 s on-time duty. Regenerated energy of 1584 kWs is converted to thermal output at a maximum braking power of 74 kW. A temperature rise limit of 65 K mandates clearance distances of 1000 mm above and 300 mm below the unit to maintain optimal heat dispersion.

Engineers appreciate how this brake resistor integrates seamlessly with frequency converters to protect against regenerative voltage spikes while dissipating excess power as heat. The natural convection cooling removes the need for auxiliary fans, enhancing system reliability and reducing maintenance. Backed by global shipping and a one-year warranty, the HLR01.1N-15K0-N08R1-A-007-NNNN is ideal for industrial drives, elevator systems, and servo applications requiring durable, high-performance braking solutions.
