Reconfigurable Actuation Control Unit Family

Moog’s line of actuation control solutions are designed to be used in multiple aerospace and harsh environments. The commercial actuation controllers fall into our Reconfigurable Actuation Control Unit (RACU) product family. This family is capable of covering a wide range of performance characteristics with varying design parameters. This new product line is derived and based on existing and qualified Moog heritage solutions that is specifically focused on lower cost, faster lead times, and a reconfigurable nature. The modularity and available of the controllers lends itself to both rapid design iteration and solution evolution.
