The power electronics provides the electricity necessary to operate the axial fans installed in the windtunnel.

All electronics (e.g. frequency converters, sine filters, etc.) for operating the windtunnel are housed in a control cabinet, the size of which is adapted to the size of the wind tunnel and its performance. The power of the wind tunnel can be adjusted between 0..100% via a 0..10V input. The control voltage can be specified, for example, using a rotary potentiometer, or conveniently using the touchpad of the wind tunnel control, which is available separately.
