The Gavita Pro 1650e LED ML is compatible with the Gavita Master controllers. It is equipped with an external e-series (Repeater Bus) adapter to which you connect power and control signal. The Gavita repeater bus control interface allows you to install 500 fixtures per controller port by simply daisy chaining the fixtures. The fixture is universal for 120-277 volt systems. Depending on the required voltage, we supply a cable with 120V plug, 240V plug, or open-end cable for industrial voltages and custom installations. The cables are connected to the e-series adapter and the fixture by means of an industrial-grade Wieland connector.
