HLT01.1N-00M6-A-007-NNIT

HLT01.1N-00M6-A-007-NNIT, Bosch Rexroth Indramat, HLT Braking Units Series

HLT01.1N-00M6-A-007-NNIT from Bosch Rexroth Indramat belongs to the robust HLT Braking Units series engineered for industrial motion control. This high-performance brake chopper safeguards drive controllers by clamping regenerated energy during deceleration, turning excess voltage into heat within an external resistor. Featuring a compact, free-mounting design, the unit integrates seamlessly alongside frequency converters or drive stacks. Its construction withstands mechanical shocks and vibrations common in demanding factory environments, ensuring continuous protection under dynamic loads.

The HLT01.1N-00M6-A-007-NNIT accepts a rated DC link voltage of 750 VDC and can dissipate up to 600 kW of braking power during high-speed deceleration. It requires a minimum clearance of 100 mm above and below the module and operates within an ambient temperature range of –10 °C to +40 °C. The unit maintains full efficiency up to 1 000 m altitude, with performance tapering at higher elevations. Constructed to IP20 degree of protection, the brake chopper must be installed in a switch cabinet rated at least IP54. Its environmental class 3K3 rating allows operation in up to 95 % relative humidity without condensation. Cooling is achieved by ambient air circulation, while the other design feature for IT nets ensures compatibility with various supply topologies.

Engineers appreciate the HLT01.1N-00M6-A-007-NNIT’s free-mounting flexibility—it can be placed on the left side of the converter with a simple 110 mm offset or anywhere space permits. Its rugged build and precise thermal management deliver reliable overvoltage protection, minimizing downtime and extending resistor life. Ideal for sustainable, energy-efficient motion systems, this brake chopper integrates effortlessly into drive cabinets to bolster safety and system resilience.
