The Bosch Rexroth MPN R911203487 (HLT01.1N-01M1-A-007-NNIT) is a brake chopper engineered for motion control systems, facilitating overvoltage protection by dissipating power—up to 1000 kW—as thermal energy into ambient air. It operates reliably within a temperature range of -10 to +40 °C and supports storage/transport between -25 and +70 °C. The unit tolerates vibration from 3 to 200 Hz and maintains functionality in environments with humidity up to 95%. Designed with IP 20 protection and dust resistance, it is not waterproof. The module should be installed adjacent to the drive controller or converter with a minimum 100 mm clearance above and below for efficient heat dissipation. A variant adapted for IT networks is available.
