Yaskawa CDBR-4045D Inverter Brake CDBR4045D

Description: 

The Yaskawa CDBR-4045D inverter brake (braking unit) is used in industrial automation systems to dissipate regenerative energy generated during motor deceleration, improving braking performance and protecting inverter drives from overvoltage conditions. Commonly installed with variable frequency drives (VFDs) in applications requiring rapid stopping or frequent braking cycles. Maintenance teams and system integrators use this braking unit for system protection, performance optimization, drive upgrades, and replacement of legacy braking units.

Applications:

The Yaskawa CDBR-4045D is commonly used in conveyors, cranes, hoists, elevators, machine tools, and heavy industrial equipment where fast deceleration and controlled stopping are required. It is ideal for applications with high inertia loads or frequent start-stop cycles that generate regenerative energy.
