Product Description:
The HLT01.1A-200K-N-007-NNNN braking unit is produced by Bosch Rexroth Indramat and belongs to the HLT Braking Units series. It is installed on the DC link of an Indramat drive package to convert excess kinetic energy into heat whenever a connected motor decelerates. This prevents overvoltage in the power section and protects both the inverter and the mechanical load.
The unit can absorb a continuous load of 200 kW, which is the amount of regenerative power it dissipates during steady braking duty. For short intervals, it tolerates a peak load of 420 kW, allowing the system to handle rapid emergency stops without exceeding thermal limits. Maintaining these figures requires an airflow of 100 m³/h through the integrated heat sink; insufficient ventilation will reduce allowable duty cycles. A minimum braking resistance of 1.05 Ω is specified so the connected resistor bank keeps current within safe margins during energy discharge. Internal electronics consume 550 W at 100% input current, a value that must be included when sizing cabinet cooling to avoid elevated ambient temperatures.
The housing width of 70 mm, height of 950 mm, and depth of 377 mm permit installation beside standard Indramat power sections while maintaining access to the top-mounted terminals. A mass of 30 kg simplifies panel mounting compared with liquid-cooled alternatives while still providing enough thermal inertia for repeated duty cycles. Power conductors fasten to an M10 threaded stud, and the recommended terminal torque of 24 Nm secures the connection against vibration. The specified geometry also leaves clearance for airflow channels, and the slim profile allows multiple braking units to be arranged in parallel when higher regenerated power must be managed across large multi-axis installations.
