variable speed drives

Enhance your application with VSDs from Greenville Electrical

Variable speed drives, also known as VSDs, are versatile devices that control the speed and torque of an AC motor by converting fixed frequency and voltage input (the mains supply) into a variable frequency and voltage output. By controlling the motor speed to precisely match the load, you can greatly improve system performance, with the benefit of soft start and stop functionality which gradually ramps up or slows down the motor speed to reduce wear and tear and promote your equipment’s longevity.


For product quality you can rely on, we supply drives from Danfoss and VACON, and take great pride in being the UK and Ireland’s largest Danfoss distributor. As a long-standing member of the Danfoss UK service partner network, we provide specific training and access to expert knowledge to benefit your business directly, including sales, service and support.
