DC Braking Unit

DC braking unit

Integrated braking unit and braking resistor on the DC bus side of AC drive, which can consumed regenerated energy from motor when motor decelerated quickly.

Application:
In generally, the braking unit and braking resistor request to install industrial application cases, which need fast stop, braking, quick stop and position request. The DC bus voltage will rise swiftly when frequency inverter decelerating, and  motor locate in generating status if the driving load is bigger. The feedback regenerated energy should be consumed quickly and keep DC bus voltage in a certain safe value, otherwise inverter will be trip of over voltage.  It is popular used in centrifugal machine, cable drawing machine. Crane, elevator…
