Braking Unit

Braking unit is particularly suitable for the applications where fast braking is required.
During the process of decelerating, regenerative energy flows from the motor into the inverter DC bus and results in increased bus voltage. Braking unit is used to convert the regenerative energy into heat and maintain the voltage of DC bus. It could improve braking performance and shorter deceleration time.

Features of Braking Unit
1. Our braking units could use average resistance, not necessary to be non-inductive resistance.
2. Our braking units could be applied for parallel operation.
