Legacy AC Drives

Variable speed drives (VSD), also known as variable frequency drives (VFD), adjust the motor speed throughout the run-cycle giving you full control of your electric motor applications. VSDs improve the life of your motors and deliver energy efficiency savings through the gentle ramping up of electrical motors.
