Product Description:

The HLR01.1N-09K5-N13R0-A-007-NNNN is a brake resistor produced by Bosch Rexroth Indramat within the HLR Brake Resistors series. Used in industrial automation drive systems, the unit dissipates surplus kinetic energy returned from a decelerating motor, preventing DC-bus overvoltage and protecting the connected inverter. By converting electrical energy into heat through its resistor network, it supports controlled braking sequences in conveyors, gantries, and machine tool axes.

During sustained operation, the resistor handles a continuous thermal load of 9.5 kW, which is the maximum heat it can radiate indefinitely without exceeding its design temperature. For short, high-stress events, it tolerates a peak dissipation of 46 kW for up to 22 s, and this interval covers rapid stops or emergency braking. The duty of these peaks is limited to an 18 % cycle, so heat must decay between events according to the 120 s load cycle. Electrical conversion is provided by a wire-wound network with a resistance of 14.6 Ω, which sets the current drawn from the DC link and influences braking torque. The aluminum housing measures 600 mm wide, 490 mm deep, and 270 mm high, providing surface area for convection while fitting standard cabinet layouts.

Thermal capacity is also characterized by an energy absorption rating of 1003 kWs, which is the amount of kinetic energy the module can convert in a single event before reaching the permissible temperature rise. When the application requires repetitive braking at 40% duty, the resistor supplies 21 kW for an allowed on-time of 48 s, providing a useful reference for cyclic processes such as indexing tables. A tinned copper terminal rated for 10 mm² conductors simplifies wiring to the drive controller and maintains low contact resistance. With a mass of 22 kg and a B3 resistor element, the unit mounts securely on panel brackets while withstanding vibration and thermal expansion.
