Product Description:
The HLT01.1N-00M5-A-007-NNIT braking unit is manufactured by Bosch Rexroth Indramat and belongs to the HLT Braking Units series. It connects between the DC bus and an external resistor array to dissipate regenerative energy that appears during rapid deceleration of servo drives or induction motors. By converting excess kinetic energy into heat instead of allowing the DC link voltage to rise, the module helps protect inverters and maintains predictable stop profiles in packaging lines, transfer systems, and other cyclic-duty automation.
An External HLR resistor is specified, so the thermal load is removed from the cabinet and can be sized for the application. The unit carries a protection rating of IP20, meaning finger-safe openings but no water-ingress protection, which suits mounting inside a closed panel. Continuous service is permitted from -10 to +40 °C, and above this limit the output current must be reduced. Installation is allowed up to 1000 m without performance loss, after which power is reduced by 1%/100 m to 3000 m. PELV insulation keeps the control circuits separated from the protective earth conductor, and EMC emission categories C2 and C3 support use in industrial zones. The device is assigned environment class 3K3, so it tolerates moderate dust and non-condensing moisture found in standard machine rooms.
The unit endures a maximum relative humidity of 95% RH without condensation, permitting operation during seasonal peaks. Mechanical resilience includes shock resistance of 4 g for 11 ms and vibration endurance of 1.5 mm / 0.6 g, allowing safe transport and cabinet mounting near production equipment. Reduced-current operation is permitted up to +55 °C, which is the stated upper limit for derated use. Protection Class 1 requires the protective-earth connection to be bonded during installation. Long-term storage is supported from -25 to +70 °C, ensuring spare units remain serviceable in storage.
Frequently Asked Questions about HLT01.1N-00M5-A-007-NNIT:
