Medium Voltage AC Drives

PowerFlex 6000 Medium Voltage AC Drives

Our PowerFlex® 6000 Medium Voltage AC Drives allow for flexibility in a variety of applications. They are suited for new and retrofit, variable torque, and constant torque applications. Some of these applications include fans, pumps, and compressors that require variable speed motor control from 2.3…11 kV. These drives are available in multiple configurations based on motor voltage and regional requirements.

PowerFlex 7000 Medium Voltage AC Drives

Our PowerFlex® 7000 Medium Voltage AC 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.

PowerFlex 7000 Drive System with ArcShield Technology

Our PowerFlex® 7000 Drive System with ArcShield™ technology is the first arc-resistant medium voltage drive with full regeneration capabilities. The arc-resistant system is certified to meet the most comprehensive set of global arc-resistant standards. This system provides an arc fault rating up to 50 kA and meets Type 2B accessibility protection standards.


PowerFlex 7000 Medium Voltage AC Drives:

Air-cooled 200…8000 Hp drives:

  • 200…5500 Hp
  • Simple but rugged, minimum component count, optimum reliability

Liquid-cooled drives:

  • 3000…8500 Hp
  • Drastically reduces control room air conditioning costs by removing 90% of the heat via a heat exchanger
  • Supports higher elevations and ambient temperatures than air-cooled drives

Extended Hp Drives:

  • Up to 34,000 Hp
  • Modular system lets you add drives—up to four drive modules in one system—until the drive power matches the application requirements
  • Suitable for hot back-up applications with an option for control redundancy
  • Uses a hub module and ControlLogix™ processors to coordinate the modular drive system.
