Compact four quadrant DC drives save energy

Compact four quadrant DC drives save energy Sprint Electric offers four quadrant DC drives that use little space and are very energy efficient. The 340XRi, 680XRi and 1220XRi DC drives are designed to regenerate energy back into the mains supply under braking without the need for complex intermediate storage, resistive dumping or additional power bridges. Four quadrant regenerative DC drives offer an extremely energy efficient system. They return the braking energy to the mains, so lowering demand from the incoming AC supply. If these drives are operated on equal driving/braking cycles, the cost of running the drive is only the electrical losses in the motor and drive.
