Sensor Switch CM-ADC Series of Automatic Dimming Control sensors provide continuous control of dimmable ballasts for daylight harvesting applications. Ideal for public spaces with windows like vestibules, corridors, or bathrooms; the CM-ADC works by monitoring daylight conditions in a room, then controlling a 0-10 VDC dimmable ballast so as to insure that adequate lighting levels are maintained. To add full On/Off switching to the dimming control provided by the CM-ADC, see the Technical Data Sheet on the CM-PC-ADC sensor. Additionally, with the Dual Zone (-DZ) option, a second customized controlled output is provided. All units are powered by 12 to 24 VAC/VDC.
