Medium Voltage AC Drives

PowerFlex® 7000 Medium Voltage Drives enable soft-starting and variable-speed control of processes with high power demands. They help reduce energy costs, component count, maintenance and motor wear.

PowerFlex 6000 Medium Voltage AC Drives

Our IEC PowerFlex 6000 Drives are particularly suitable for new and retrofit centrifugal fan and pump applications. These drives provide cost-effective solutions for motor control applications from 200 kW to 5600 kW and for motors rated from 3 kV to 10 kV. To achieve the low input harmonics and near-unity power factor that make this an ideal solution for standard motors, these drives use Cascaded “H’” Bridge (CHB) topology. This topology combines an integrally mounted, phase-shifting isolation transformer with series-connected power modules for each phase.

PowerFlex 7000 Medium Voltage AC Drives

PowerFlex® 7000 Drives are air-cooled or liquid-cooled drives available in a broad power range of 200…34000 Hp and supply voltages of 2400…6600V AC. These general purpose, stand-alone drives control speed, torque, direction, starting, and stopping of standard asynchronous or synchronous AC motors.
