The ABB NBRA-659C is a high-performance brake chopper unit specifically designed for seamless integration with ABB’s ACS800 series of industrial drives. This essential component manages regenerative energy generated by the motor during deceleration or braking operations. By connecting an external braking resistor to the drive’s DC bus, the NBRA-659C effectively dissipates excess energy as heat, preventing overvoltage faults and protecting the drive from potential damage. Its robust design ensures reliable and safe operation in demanding applications involving high inertia loads or frequent start-stop cycles, enhancing the overall stability and performance of the drive system.
