MotionController – GEL 8400

Controller for 6 axles

The GEL 8400 MotionController has been optimized for the harsh environment of wind turbine rotor hubs, and meets all the requirements of installation locations worldwide – both onshore and offshore. It is available as a Hot Climate Version (HCV) for the warm, humid climate of southern China, or as a Cold Climate Version (CCV) for use at -20 °C at an altitude of 1,500 meters on the Central Asian plateau. As the successor model to the tried and tested GEL 823x and GEL 825x, the new GEL 8400 combines years of experience with the enhanced performance of this product family.
