Regenerative
May 1st 2005 Sprint Electric 340XRi, 680XRi and 1220XRi DC drives offer a solution to four quadrant regenerative drive applications. Using little panel space and mounting on standard DIN rail, these drives are for use with motors up to 1.8kW 2Hp.
The XRi drives are able to regenerate energy back into the mains supply under braking without the need for complex intermediate storage, resistive dumping or additional power bridges. With four quadrant operation, the torque can be reversed gently or almost instantly, as required. More articles from Sprint Electric Ltd: |
