The connection box with electronic phase changer is one of many components in the DUOline rail system and provides an electrical connection between the power connection and the DUOline system. The 2-phase system is extremely flexible and offers many possibilities for individual lighting design. The junction box with electronic phase changer can be used as medium or final supply and has a maximum load capacity of 200 watts per phase. The connection box with an electronic phase changer makes it possible to change the system in two lighting groups even with a standard 3-wire cord.
