Twilight switches switch electrical consumers on when it is dark and off again when it gets 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. Properties: large setting range from 1 lux ... 200 lux and high switching stability, fast and precise setting of the switching values through logarithmic characteristics and instantaneous LED, largely insensitive to optical feedback through fixed hysteresis, no unwanted switching in the event of a short-term change in the ambient brightness, 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, mounting type: surface-mounted housing for wall mounting indoors and outdoors. When using the optionally available mounting set, mast or pipe mounting is also possible. Areas of application: Control of lighting on streets, buildings and industrial sites. Notes: Product designation we for white housing. an for anthracite-colored housing.
