Medium Voltage Drives

Rockwell Automation manufactures three medium voltage drive types – all of them are CSI topology. The main differences between types are: power range, input section configuration, cabinets design – footprint, cooling and control voltage.

There are few manufacturers of medium voltage drives. Each of them offers different drive topologies with specified advantages and drawbacks. In successively published posts I will provide brief product specification and links to available documentation. At this point I will not compare specific solutions.
In the following posts I will present offer of companies with the [...]
