Model No: CDBR-4045C
Dynamic Braking Unit for Solar Pump VFD
The function of the CDBR braking unit is to divert into a braking resistor the regenerative energy produced in the process of decelerating the motor, converting that energy into heat. Regenerative energy flows from the motor into the inverter DC Bus, manifested as increased bus voltage. The advantage gained using the CDBR is improved braking performance and shorter deceleration time of the load.
