HLR01.1N-34K0-N0R45-A-007-NNNU

The Bosch Rexroth Indramat HLR01.1N-34K0-N0R45-A-007-NNNU from the HLR Brake Resistors series delivers dependable braking performance with a continuous output of 34 kW and a DC Bus Nominal Voltage of DC 700 V. This compact resistor features a resistance of 0.45 ohm and a rugged Type N construction designed for free assembly. Certified to IP20 protection, the unit incorporates flameproof elements and high dielectric strength resistive coils to withstand extreme pulse loading. Cooling is achieved through natural airflow from the converter, minimizing thermal hotspots and extending component life.

Engineered for seamless integration with Bosch Rexroth HCS converters, the HLR01.1N-34K0-N0R45-A-007-NNNU relies on a brake chopper in the drive controller to convert regenerative energy into heat. Designed for installation directly above the converter inside the control cabinet, this resistor occupies minimal panel space thanks to its compact size and space-saving design. Its fully encapsulated housing and robust steel framework ensure long-term durability under continuous operation, while the included one-year warranty provides added service assurance.

During installation, maintain the manufacturer’s recommended clearances—horizontal, top, and bottom—to prevent damage from the significant heat dissipation this device generates. Always secure the resistor to the equipment grounding system and avoid mounting near combustible materials, as the surface temperature can rise substantially during heavy regeneration cycles. With proper spacing and grounding, the Bosch Rexroth Indramat HLR01.1N-34K0-N0R45-A-007-NNNU offers a reliable, low-maintenance solution for high-energy braking applications.
