Product Description:
The HLR01.1N-23K0-N05R5-A-007-NNNN is an external brake resistor built for the HLR Brake Resistors series produced by Bosch Rexroth Indramat. This component links to regenerative drives and dissipates surplus DC-bus energy as heat when a connected servo axis decelerates. By converting kinetic energy into thermal loss, the resistor helps prevent DC overvoltage trips and keeps the drive system within its allowable operating window during rapid motor braking or repeated load reversals. This type of resistor is used where braking energy cannot be returned to the supply and must be dissipated outside the drive housing.
The continuous braking duty is rated at 23 kW, meaning the unit can absorb that thermal load without exceeding its temperature limit during steady deceleration cycles. For emergency or short-term stops, the resistor withstands a peak of 109 kW, giving the connected drive more headroom when high-inertia axes must be stopped quickly. That peak can be applied for up to 22 s before cooldown is required. Over a single braking event, the module can store and dissipate 2429 kWs of energy, which helps verify that the braking profile will not overheat the resistor matrix. This operating range suits machines with aggressive indexing, frequent deceleration, or elevator-style motion.
The steel enclosure weighs 56 kg, so cabinet shelves or wall brackets must support that load. A vertical height of 710 mm supports convection airflow above the resistor, while the 595 mm width leaves room for side clearances in typical panel layouts. Front-to-back depth is 490 mm, allowing the unit to fit in standard 600 mm deep enclosures with space for wiring bends. The enclosure footprint is intended for cabinet installation where airflow and cable routing space must be preserved around nearby components.
