AS7210 Smart Daylighting Manager

Standalone daylight sensing and integrated luminaire management


AS7210 is a highly-integrated Smart Lighting Manager with an embedded digital ambient light sensor (ALS). This provides single-device, closed-loop and automatic adjustment of the brightness of florescent and LED lamps and luminaires to maintain constant lux in response to available daylight. For streamlined system integration, luminaire control is through direct connection to 0-10V dimmers, with control outputs that include direct PWM to LED drivers or analog 0-10V to standard dimming ballasts.
