Highly developed and continually tested electronic engineering is a prerequisite for efficiently and reliably regulating full-power converters. The VENSYS Controller Board regulates full-power converters ranging from 1.5 MW to 6 MW output and has been working successfully in VENSYS converters as well as in wind turbines of licence holders around the world for many years. The VENSYS Controller Board is manufactured and tested in our in-house electronics department.
