Schneider Electric Altivar Variable Speed Drives

Schneider Electric Altivar Variable Speed Drives (VSDs) regulate the rotation speed of an electric motor and power pumps, fans, and other mechanical components. These drives are available at various speeds, and the most common are variable frequency drives (VFDs), which are widely used to control AC motors in most applications. The primary use for both VSDs and VFDs is to vary the frequency and voltage supplied to the motor. In turn, these varying frequencies control a motor's acceleration, change of speed, and deceleration. VSDs and VFDs reduce power consumption when the motor is not needed, boosting efficiency. VSDs, VFDs, and soft starters offer a wide range of fully tested and ready-to-connect motor control solutions, up to 20MW. These products from Schneider Electric meet the demanding needs for industrial processes, machines, and building applications.
