The Medusa™ Series of digital flipping and lighting controllers solves the headaches traditionally associated with lighting flippers. Not only does the Medusa™ Series flip lights, it's also a lighting controller, essentially being two products in one. Your ballasts and reflectors all plug into one unit! The digitally based design of the controller allows for the Medusa™ to properly flip and control your lights. An easy to use trigger cord is plugged into the Apollo® series timer (included) to control the switching between light banks. When powered ON, Medusa™ is powering bank A by default. Once the trigger cord has been activated according the user defined timing pattern, the digital part of the controller goes to work. With precision timing, the Medusa™ will turn OFF power to the ballasts, switch the relays to bank B and then reapply power to the ballast, light bank B. This controller also incorporates Titan Controls® patent pending top off design for easy installation. Features a powder coated steel enclosure that is designed for the harsh gardening environment. When 'Failure is not an option", use Titan Controls®!
