A braking chopper is an essential component in dynamic braking systems for variable frequency drives (VFDs), helping manage regenerative energy during motor deceleration and overhauling operation. Dufew Electric provides CBU Series braking choppers designed for compatible 220V, 380V, and 690V drive systems.

Dufew provides the Braking Chopper as an external dynamic braking solution for variable frequency drives (VFDs), helping control DC bus voltage when motors operate as generators during rapid deceleration or overhauling loads. Designed for 220V, 380V, and 690V drive systems, the CBU Series can be configured according to braking power, duty cycle, DC bus voltage, resistor specifications, and installation requirements.

Filters are the selective gates of electronic systems, passing desired frequencies while rejecting others.

A reactor—or inductive component—serves as the energy storage element in power electronics, essential for filtering, smoothing, and impedance matching.

The resistor is the most fundamental passive component in electronics, yet its role is often misunderstood.
