Reconfigurable Actuation Control Unit

Reconfigurable Actuation Control Unit Family

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