Product Description:

The HLR01.1N-02K0-N15R0-A-007-NNNU brake resistor is produced by Bosch Rexroth Indramat within the HLR Brake Resistors series. It is connected across the DC bus of a servo or frequency inverter and converts surplus kinetic energy into heat whenever an axis is brought to a stop. By absorbing this energy outside the drive controller, the device helps protect IGBTs and capacitors during repeated deceleration events. This makes it suitable for braking cycles in packaging, gantry, and material-handling equipment where regenerated energy must be dissipated in a controlled way.

Electrically, the unit is rated for a continuous braking power of 2 kW, meaning it can dissipate that thermal load without exceeding its permitted surface temperature. The element presents a resistance of 40 Ω, which determines the current drawn from the DC link during braking. During one braking event, it can accept an energy pulse of 137 kWs. That pulse may be applied for up to 3.4 s at a time, after which the resistor must cool before the next heavy braking event. The permissible duty cycle is limited by a maximum on-time of 120 s, so the drive must allow recovery periods between extended braking sequences.

The mechanical format supports those thermal figures without requiring active ventilation. Total height is 749 mm, width is 185 mm, and depth is 120 mm, giving a slender profile that fits beside drives in a control cabinet while exposing a large surface for convection. A mass of 6.2 kg helps slow temperature rise during short energy dumps. The dimensional arrangement also leaves room for cable connections and helps keep exhaust heat away from nearby control components.
