The CMRB PC ADC Series combines the CMRB PC On/Off Photocell sensor with the CMRB ADC Automatic Dimming Control sensor to provide the industry's most intelligent control of lighting for daylight harvesting applications. Ideal for public spaces with windows like vestibules, corridors, or bathrooms; the sensors work by monitoring daylight conditions in a room, then controlling the lighting so as to insure that adequate lighting levels are maintained. The CMRB PC ADC Series sensors are line powered and can switch loads directly without the need for a Power Pack. The CMRB PC ADC's enclosure is specifically designed to mount on the end of a linear fluorescent fixture.
