HLB01.1D-02K0-N03R4

The Bosch Rexroth Indramat HLB01.1D-02K0-N03R4 from the HLB Resistor Brake Units series features a wide Input Voltage 254–750 Vdc range and delivers an Output power 2 kW continuous rating alongside a Short Circuit Current Rating 42 000 A for reliable performance. This resistor brake unit also offers a maximum braking power 100 kW capacity to handle abrupt deceleration of high-inertia loads, while its braking power duration 2 kW ensures consistent energy dissipation under extended duty. Built into a compact chassis measuring 100 mm in width, 440 mm in height, and 309 mm in depth, the unit conserves panel space without sacrificing robustness. A built-in DC bus short circuit system acts as a safety interlock, instantly disconnecting synchronous motors in the event of bus irregularities or power failure.

Energy management is optimised through a heavy-duty architecture that supports energy consumption 500 kW and enables rapid deceleration of high-rpm motors. The kinetic energy recovered during braking is safely stored in an integrated battery module, boosting both continuous and peak regenerative power and reducing overall system load. High-inertia applications benefit from the unit’s ability to absorb surges without derating, delivering consistent braking torque throughout varying speed profiles. The robust design minimises thermal stress, ensuring long operational life in demanding production environments.

As a versatile, autonomous platform, the HLB01.1D-02K0-N03R4 excels in metal machining, automotive parts manufacturing, and other motion-control applications that require precision deceleration and energy recycling. Its compact footprint, advanced safety features, and high-power capability make it an ideal choice for system integrators and OEMs seeking a cost-effective yet reliable resistor brake solution. With Bosch Rexroth Indramat quality and service backing every unit, this brake module promises seamless integration and dependable operation in the most challenging industrial settings.
