Allen-Bradley PowerFlex 6000 drive from Rockwell Automation has two new output-voltage ratings – 6.9 kV for North America, and 11 kV for EMEA and Australia.0
Allen-Bradley PowerFlex 6000 medium-voltage AC drives from Rockwell Automation offer expanded, user-friendly control for variable and constant torque applications. The latest release delivers a wider voltage range (2.4 to 11 kV) and provides 100 percent starting torque, leveraging sensorless vector control. The PowerFlex 6000 drive is easy to commission, use and maintain, with standard faceplates and EtherNet/IP connectivity. The drive is a cost-effective solution for heavy industries with higher power needs for their applications. The drive can be used for applications with output-voltage ratings up to 11 kV and motor current ratings up to 680 A, while remaining an air-cooled design. With eco-designed main cooling fans, users in Europe and other IEC-based markets can meet EC regulation 327 and ErP directive 2009, and avoid the larger footprint of a liquid-cooled drive. Internally powered cooling fans reduce customer-supplied control power requirements, and equipment and installation costs. A tertiary winding on the isolation transformer provides internal power for the fans.
