Product Overview
The CDBR-4090D is a high-power dynamic braking unit developed by Yaskawa Electric, specially designed for supporting 400V-class high-power industrial inverters. With a 90A rated braking current and 40Ω standard resistance configuration, it efficiently consumes regenerative kinetic energy generated by motor rapid deceleration, braking and sudden stop. It effectively solves common industrial problems such as DC bus overvoltage, unstable braking performance and slow equipment shutdown caused by high-speed motor operation. Featuring reliable passive energy dissipation design and built-in overheat and overcurrent protection, it ensures safe and stable long-term operation in high-load automated scenarios. Adopting standard IP20 cabinet-mounted structure, it enables convenient installation and wiring matching Yaskawa high-power inverter systems. Widely applied in lifting, metallurgy, printing and heavy-duty automation equipment, it provides stable and efficient braking control solutions for system integrators and plant maintenance teams.
