EP means reliable, durable and easy to maintain
The encapsulated powerpole of the SC9000 EP variable frequency drive yields a high MTTF, even in severe environments such as wastewater, mining and oil & gas. Its patented environmental protection and three-level neutral point clamped (NPC) topology improves reliability and diminishes the need for repairs.
Burned in and tested to ensure top quality
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.
When the SC9000 EP variable frequency drive is outfitted with a Synchronous Transfer System it is able to perform a closed transition maximizing capital efficiency by operating multiple motors of varying Hp with one single drive. The incorporation of Ampgard motor control with the double bus design ensures superior performance.
Integrated control gear streamlines multi-configuration lineups
Compact and economical solution combining Eaton’s Ampgard main breaker and motor starters with the SC9000 medium-voltage drive across a common bus in a single high quality, integrated assembly. Entire assembly is available as arc-resistant.
