Eaton's Synchronous Transfer System maximizes capital efficiency by operating multiple motors of varying hp with one single drive. The incorporation of Ampgard motor control with the double bus designs ensures superior performance. Learn more about synchronous drives transfers and benefits.
Energy efficiency is a powerful incentive to incorporate variable frequency drives but there is another major benefit to applying drives in medium-voltage applications: do more with less equipment. Learn 5 ways synchronous transfer VFDs reduce equipment costs and improve system reliability.
Each SC9000 EP medium-voltage VFD receives a burn in test with full voltage and current for a duration of up to 24 hours while connected to a fully rated medium-voltage motor.
