OVERVIEW
Hubbell Building Automation’s DLC7 is the ideal system for providing continuous dimming control for 0-10V dimming ballasts based on natural daylight. The DLC7 maintains constant, undisturbed fluorescent light levels during peak use. Through continuous monitoring of ambient light levels, the DLC7 dims the associated lighting fixtures to a user pre-defined foot-candle setting to provide additional illumination in order to compensate for a lack of natural light on the work surface (e.g. desktop, floor). The DLC7 (0-10VDC) dimming photocell provides precise control of the actual amount of illumination on the work surface within its field of view. Measured light levels are converted into a linear proportional analog voltage that controls the ballast dimming range. This allows for maximum energy savings by efficiently blending natural and artificial light to maintain a comfortable visual environment. The sensor head adjustment sets the maximum output of the controlled ballast. The linear response of the DLC7 allows the user to make accurate adjustments between 7 and 140 foot candles. The sensor also provides a short or long delay. The short delay provides for faster sensor response, whereas long delays slow the sensor response and maintains a more stable signal to the ballast (e.g. passing clouds).
