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
- Easy installation
- High instantaneous braking capability
Designed for both single drive configurations and common DC bus drives
