ABB ABRC-01C Brake Chopper Control Board – ACS800 Braking Unit – Tested

Product Overview

Original ABB ABRC-01C brake chopper control board for ACS800 series drives. Monitors DC bus voltage and controls the braking IGBT to dissipate regenerative energy through an external braking resistor during motor deceleration. Prevents DC bus overvoltage and protects drive components from damage in high-inertia applications. Supports communication with higher-level automation systems via Modbus-RTU, Profibus, and CANopen protocols.
