Rockwell Automation has extended its PowerFlex 755 AC drives to 900 kW and added 600/690 volt ratings.
The new drives, designed for use in heavy industrial processes, provide users with increased flexibility, advanced diagnostics and a common DC bus option.
The PowerFlex 755 is designed for applications ranging from simple speed and variable torque control to the most demanding systems requiring constant torque control.
Applications include fans, pumps, mixers, compressors, conveyors and extruders.
Like other PowerFlex 755 drives, this latest frame size includes an embedded Ethernet port and five option slots so that users can tailor it to their requirements.
Optional modules include I/O feedback, safety, additional communications and an auxiliary power supply.
A roll-out design allows easy access to the drive for fast installation and maintenance.
The drive’s converter and control pod can remain in the unit while the inverter is rolled out ensuring that control wiring remains connected.
