Power MOSFET with an almost unlimited number of switches up to 400 W. Automatic lamp detection. Standby loss of only 0.3 watts. Dimming to minimum and maximum brightness, as well as soft on/soft off for lamp switching, can be additionally adjusted. Digitally adjustable and fully electronic multifunction time relay for lamps up to 400 W, depending on ventilation conditions. Dimmable energy-saving lamps and dimmable 230 V LED lamps are also dependent on the lamp electronics. If the minimum brightness is not set to 0, it will not turn off but will dim to the set percentage value. Up to 3600 W with power supplements LUD12-230 V at terminals X1 and X2. Universal control voltage locally 8..230 V UC and additionally universal voltage control inputs 8..230 V UC for central on and central off. The control inputs are galvanically isolated from the supply and switching voltage of 230 V. Switching at zero crossing to protect the lamp. From 110 V control voltage glow lamps.
