Product Description:
The HLR01.1N-24K0-N07R2-A-007-NNNN brake resistor is manufactured by Bosch Rexroth Indramat and belongs to the HLR Brake Resistors series. It mounts next to regenerative drives to absorb surplus DC-bus energy generated when motors decelerate or reverse. By turning excess electrical energy into heat, the unit keeps link voltage within safe limits and supports rapid, repetitive braking sequences used in packaging lines, material-handling gantries, and machine-tool spindles. Because the resistor works as a passive energy sink, it requires only power connections, which simplifies integration in both new and retrofit control cabinets. This operating role also helps reduce nuisance overvoltage shutdowns during aggressive deceleration cycles.
During each braking event, the module can dissipate up to 24 kW of power, which is the thermal load the resistor grid can withstand without exceeding its allowable temperature. Its element presents 83 Ω to the link circuit, which determines the instantaneous current when the chopper transistor conducts. For cyclic duty, the device accepts an energy total of 2592 kWs over a continuous period of 31 s, so a programmed motion profile can remain within the allowable energy budget. When applications demand extended engagement, the specified ceiling of 120 s maximum on-time marks the absolute limit before a cooling pause is required to protect resistor integrity. The resistance value also affects how strongly regenerative energy is drawn away from the DC bus during braking.
The assembly weighs 80 kg, giving it thermal inertia for intermediate heat storage while requiring rigid support brackets. Cabinet layout must reserve a clear envelope with a height of 710 mm, a width of 795 mm, and an installation depth of 490 mm. Free space around the housing supports natural convection, and that spacing helps heat move away from nearby wiring and control components. A layout that respects these dimensions also leaves better access for inspection and cleaning inside the enclosure.
