1-phase liquid-cooled brake chopper units

Brake choppers are used for resistor braking. They handle the energy generated by decelerating motors for example in emergency stopping. The on/off controlled chopper connects the brake resistor to the DC bus whenever the voltage in the bus exceeds the limit defined by the control program.


  • Power ratings:
    Maximum continuous braking power, Pbrcont: : 119 to 714 kW / 690 V
    Maximum short time braking power, Pbrmax: 404 to 2422 kW / 690 V
  • Compact
  • Easy installation
  • High instantaneous braking capability
  • Designed for both single drive configurations and common DC bus drives
