Medium-voltage motor control systems

SC9000 CI medium-voltage variable frequency drive

Designed for use with 4160 V induction or synchronous motors up 2500 hp, the SC9000 CI medium-voltage variable frequency drive delivers the reliable performance and energy savings you expect from an SC9000 VFD but in up to 40% less floorspace! The SC9000 CI drive positions the optional output filter above the inverter, delivering a small footprint especially when long cable lengths are required. The SC9000 CI medium-voltage drive is a fully integrated drive with main bus, isolation switch, power fuses and vacuum contactor. 

Voltage class
5 kV
Horsepower
up to 2500 hp
Main bus rating
up to 3000 A

Core features

  • Certified to UL 347A
  • Compact footprint for space constrained applications
  • Eaton’s exclusive “Soft-Mag” pre-charge system to eliminate transformer inrush current, simplify protection and improve long-term reliability
  • Utilizes an inverter topology with a three-level neutral point clamp (NPC) for a low part count and high reliability
  • 24-pulse isolation transformer for IEEE 519 standard compliance
  • Fully-integrated design includes an isolation switch, power fuses and a main contactor eliminating the need for a remote feeder — reducing capital investment.
  • Roll-in/roll-out stab design inverter for convenience and time savings during inspections and maintenance
  • Full factory testing and burn-in utilizing medium-voltage motors — as opposed to load banks — in Eaton’s world-class motor room
  • Combines with Eaton’s Ampgard main breaker and motor starters across a common bus into a compact and economical integrated assembly

Discover how Eaton SC9000 EP arc-resistent medium-voltage drives safely protect your team and bottom line.

Efficient use of your most valuable resources

The industry leading compact design of the SC9000 CI drive is also equipped with the lowest inverter part count and low mean time before failure (MTBF) increasing reliability for your operation. Further benefits include a low total cost of ownership with component level spares and a roll in/roll out inverter design simplifying maintenance activities.

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
