NBRA-653C ABB High-Performance Braking Chopper

Description:

The ABB NBRA-653C is a high-performance braking unit designed for use with ABB's ACS880 series inverters. Its core function is to dissipate regenerative energy generated by the inverter during motor deceleration or load inertia, preventing the inverter's DC bus voltage from overshooting. This protects the inverter and ensures stable and reliable operation of the drive system.

Features：

• Digital and Analog I/O

Capable of handling both digital and analog signals, making it versatile for different types of applications.

• Condition Monitoring and Protection

Built-in temperature monitoring and protection functions. If the braking resistor temperature exceeds a certain limit, a signal is sent to the inverter, which then adjusts the braking strategy or issues an alarm to prevent equipment damage.

• Overvoltage Protection

Its core function is to maintain the inverter's DC bus voltage within a safe range, preventing overvoltage faults caused by regenerative energy.

• High Reliability

Engineered for high performance and reliability in industrial environments
