has recently extended its PowerFlex 755 AC drives to 900kW and added 600/690V ratings.
The drives are designed for heavy industrial processes and are said to provide users with increased flexibility, advanced diagnostics and a common DC bus option.
This latest frame size includes an embedded Ethernet port and five option slots. Optional modules include I/O feedback, safety, additional communications and an auxiliary power supply.
The drives are ideal for simple variable speed, variable torque control and demanding system applications including fans, pumps, mixers, compressors, conveyors and extruders.
According to the company, a firmware upgrade for the drives will contain Interior Magnet Motor Control which delivers increased application flexibility and high energy efficiency.
A Stop Dwell feature allows users to pre-configure the motor to perform a controlled stop.
