OVERVIEW
Hubbell Building Automation’s daylighting control photocell sensors (DLCPCI, DLCPCO, DLCPCA and DLCPCS) and the DLCPCC photocell controller provide indoor, outdoor, or skylight control of lighting circuits based on natural daylight. Utilizing these two foundations the DLCPC sensors and controller are able to provide coverage for any application. The DLCPC photocell sensors and controller convert light level measurements to an analog signal that is sent to a energy management system (EMS) to control area lighting by switching banks of lights on and off, or to provide continuous signals to electronic dimming ballasts for fluorescent fixtures.
The sensor sensitivity is adjustable. The maximum output voltage can be matched to the maximum light level, in order to provide the highest resolution signal to EMS. Model measurements ranges include 750, 2,500 or 7,500FC. The indoor sensor has a flat Fresnel lens that looks downward in a 60-degree cone of reference to measure actual light on the work surface. The outdoor sensor is enclosed in a weatherproof housing with a visor for shading and lens protection. The Atrium and Skylight sensors both use diffusing dome lenses to provide a 180-degree angle of photodiode response.
