Finder Twilight switch 1 pc(s) 11.91.8.230.0000 Operating voltage:230 V AC Light sensitivity: 2 - 150 lx

Twilight switch with integrated timer clock function for power saving (switch-off/reduction of light during a few hours of the night). Additional, light-controlled output for controlling the power module type 19.91.9.012.4000. Compensation of the effect of the switched light: Switch-off of the lamp through the brightness of the switched light is avoided by measuring the light intensity after about 10 minutes and storing it as a reference value. This is helpful when it is not possible to install the twilight switch outside of the switched light. This is indispensable when using gas-discharge lamps, which become bright very slowly. Undesired switching on and off is avoided. With LCD display for set-up, programming and status. Internal battery for setup, programming, status, power reserve and maintaining the programme when the operating voltage fails.
