Twilight switches electrical devices on when it gets dark and off again when it becomes bright. The devices of this series have a fixed set hysteresis. The twilight value at which the lighting is to be switched on can be adjusted. It is turned off at 1.5 times this value. The casing color is white or anthracite, depending on the design. Features: Large adjustment range of 1 lux . 200 lux as well as high switching stability; fast and precise setting of the switching values through logarithmic characteristic and instantaneous LED; extensive resistance to optical feedback due to fixed hysteresis; no undesired switching if the ambient brightness is changed for a short time; temporary suppression of the switching delay after setting for immediate load check; robust switching contact allows switching of parallel compensated illuminants; large connector space and cable entries for easy cable connection. Mounting type: surface-mounted housing for indoor and outdoor wall mounting. When using the optionally available fixing set a mast or Pipe mounting possible. Applications: Controlling lighting of roads, buildings and industrial buildings. Notes: Product name "WE" for white housing. "ON" for anthracite colored housing.
