Rockwell Automation PowerFlex 400 AC Drives

A series of compact AC drives PowerFlex 400 from the company Rockwell Automation (Allen-Bradley) It was developed specifically for controlling asynchronous motors as part of ventilation, air conditioning and pumping systems, with a wide power range (up to 250 kW). As a tool for adjusting the rotation speed of the electric motor, the sensorless method of volt-frequency regulation is used. The built-in profile settings make it easy and simple to put them into operation and configure the converters according to the selected application specifics.

The model range is represented by six types of dimensions, two types of network voltage parameters are available for order. All models have a user-friendly operator interface, software tools for remote parameterization. Additional equipment attributes can also be provided on request to ensure protection and isolation of the drive from interference, remote control and other options.
