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.

Inrush current, meet your match

SC9000 family of medium-voltage VFDs utilize Eaton's soft-mag pre-charge system which:

Eliminates drive inrush current
Simplifies protection and coordination
Provides a possible reduction of incident energy and PPE level at the drive

Synchronous transfer to maximize efficiency

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.
