RC5 Regenerative Unit

5 - 100 HP Regenerative Unit

The RC5 was one of two line-regeneration products offered by Yaskawa. The RC5 was a cost-effective solution that could replace braking transistor/resistor networks in high duty cycle braking applications.

The RC5 was ideal for applications that had large overhauling loads or made frequent stops such as elevators, centrifuges, test stands, and winders (but do not have input harmonic distortion requirements).

The RC5 Regenerative Unit is a Legacy product and is no longer promoted in the Americas.
