ACS880-607 Brake Chopper and Brake Unit

Brand: ABB Group

Brake choppers and brake units are used for resistor braking. 

They handle the energy generated by decelerating motors for example in emergency stopping. 

Whenever the voltage in the drive’s common DC bus exceeds a certain limit, a braking chopper connects the bus to a braking resistor.
Features
  • 1-phase brake choppers are on/off controlled
  • 3-phase brake units are dynamically controlled
  • Designed for common DC bus drive systems
  • Customized product that fulfills your needs
