Dynamic Brake-Manager DBM 4.0


The device acts as a brake chopper in DC links, which means that the DBM 4.0 switches onto a safe brake resistor when the set voltage is exceeded, thereby diverting braking energy from the system in a highly dynamic manner. The DBM 4.0 can be attached to individual drive controllers as well as multi-axis systems or larger DC networks. Its key features are integration capacity, performance and communication skills. Depending on the application, the Dynamic Brake Manager DBM 4.0 can be provided as an individual device or in conjunction with a safe brake resistor, also provided from Koch.
