Availon, Inc., introduces a redesigned, robust, and cost-efficient pitch controller. The premise for the extensive re-design was customer feedback and the ability to do a root cause analysis by Availon’s engineers, who singled out several issues, including: communication problems; damages caused to the controller’s circuit board by the constant vibration and environmental contaminates; damages to the controller and the controlled components from voltage spikes; and the disparity between specified temperature range and actual operating environment.

To minimize turbine failures, the new design features robust and reliable communications from the pitch controller to the axis cabinet components. Circuit boards are specially coated to prevent loosening due to vibration and to guard against corrosion. Improved RS communications now provide a higher tolerance for voltage spikes. Upgrades to the controller’s components also allow it to handle a wider temperature range.
