Power MOSFET with an almost unlimited number of circuits up to 400W. Automatic lamp detection. Standby loss only 0.3 watts. Dimming to minimum brightness and maximum brightness as well as soft on/soft off when switching the lamp can also be set. Digitally adjustable and fully electronic multi-function time relay for lamps up to 400W depending on the ventilation conditions and the dimming type. Dimmable energy-saving lamps and dimmable 230V LED lamps also dependent on the lamp electronics. If the minimum brightness is not set to 0, the lamp is not switched off but dimmed to the set percentage value. Up to 3600W with power boosters LUD15-230V on connections X1 and X2. Universal control voltage locally 8..230V UC and additional universal voltage control inputs 8..230V UC central on and central off. The control inputs are galvanically isolated from the 230V supply and switching voltage. Zero-crossing switching to protect the lamp. Glow lamp current 5mA from 110V control voltage. Automatic electronic overload protection and overtemperature shutdown. Both the function and the times are entered using the two MODE and SET buttons and shown digitally on an LC display. When setting the time, all values can be entered within the preselected time frames (0, 1 to 9, 9 or 1 to 99 seconds, minutes or hours). The longest time is 99 hours. This makes 600 time settings possible. The entered time(s) is (are) constantly displayed digitally.
