The universal connection box 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 universal supply can be used as medium or final supply and has a maximum load capacity of 600 watts per phase. To use the universal input, a 4-wire power line is required to enable separate switching or dimming of the two phases. The various circuits can be established with either a series switch or two separate wall switches or dimmers. The system is available in three different color variants, here in titanium color.
