Daylight Harvesting & On/Off Photo Sensors - Low Voltage

Model: ILC-SWX-250-1-D

Intelligent Lighting Controls photocell sensors control lighting according to measured ambient lighting in a space. Basic on/off units signal a connected power pack to turn lights off when ambient levels are high enough that desired overall light levels are maintained. Units with the daylight harvesting (dimming) option track a space’s overall illumination and dim connected lighting to achieve energy savings. During times of high daylight contribution to a space, controlled artificial lighting will be gradually dimmed to a minimum dimmed level.  During times of no or low daylight contribution, controlled artificial lighting will increase back up to its maximum level. The sensor can also be configured to signal a connected power pack to switch lighting off completely in maintained high daylight conditions. Additional configurable parameters include high & low trim levels and fade rates. All photocells provide the option of selecting the ambient light threshold (e.g., setpoint) from a range of preset values or running an auto-selection mode where the unit will determine the setpoint based on the measured amount of light it is controlling.
