Twilight switches switch electrical devices off when it is dark and on again when it is light. The devices in this series have a fixed hysteresis. The twilight value at which the lighting should be switched on is adjustable. The switch-off occurs at 1.5 times this value. The housing color is white or anthracite, depending on the model. Dasy TC have an integrated timer. This means that in addition to the twilight function, the lighting can also be switched on and off at specific times. Features: - integrated timer for energy-saving and convenient switching on and off of the lighting, - easy-to-read, temperature-stable LED display with intuitive menu navigation and rotary/push button, - simple, intuitive setting of times and options, - large storage capacitor for buffering the time for several days, - no time transmitter required thanks to quartz-stable circuitry, - configurable, automatic summer/winter time changeover - large setting range from 1 lux...200 lux and high switching stability, - fast and precise setting of the switching values thanks to logarithmic characteristics and undelayed LED, - extensive insensitivity to optical feedback thanks to fixed hysteresis, - no unwanted switching when the ambient brightness changes briefly, - temporary suppression of the switching delay after setting for immediate load checking, - robust switching contact allows switching of parallel compensated lamps, - large connection space and cable entries for easy cable connection Installation type: surface-mounted housing for wall mounting indoors and outdoors. When using the optionally available mounting kit, mast or pipe mounting is also possible. Areas of application: Control of lighting on streets, buildings and industrial sites. Notes: Product name 'we' for white housing, 'an' for anthracite-colored housing.
