WSTBU Breaking Unit

Product introduction:

The function of the 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 braking unit is improved braking performance and shorter deceleration time of the load.
