Twilight switches are switches that switch electrical devices on when the light falls below a lower value and switch them off again when the light exceeds an upper value. Doepke twilight switches are available in versions for external installation, but also for installation in distribution boards with an externally mounted light sensor. The devices in the Dasy series are twilight switches with a fixed hysteresis. A rotary potentiometer allows the pre-selection of the twilight value at which the lighting should be switched on. The lighting is then switched off at 1.5 times the brightness of the set value. Properties: - large setting range of 1 lux ... 200 lux and high switching stability - fast and precise setting of the switching values through logarithmic characteristics and undelayed LED - extensive insensitivity 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 parallel switching of 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 set, mast or pipe mounting is also possible. Areas of application: control of lighting on streets, buildings and industrial sites.
