The following devices/interfaces are used to control the color and brightness of the Monochromatic LED through DALI2 / PUSH 1-10V signal. These devices need a 24Vdc power supply Not Dimmable (type S.2405, S.2406, S.2445 and S.2446) and must be placed between the 24Vdc power supply and the luminaires. Therefore choose a 24V power supply based on the maximum power used of the luminaires up to a maximum of 144W. IP20 Dimensioni 132mmx22mmx19mm
