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.
The SC9000 CI drive incorporates the same highly reliable neutral-point clamp topology as the SC9000 EP drive in addition to:
