The 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.
