Hubbell’s Daylight Tracker – DHT is a unique photo-sensing
device that utilizes available daylight, saving on energy
costs in rooms that are adequately lit. When installed,
sufficient daylight will automatically signal the Tracker to
selectively deactivate the lighting. A dimming unit, model
DHTD senses ambient light and dims IC controllable
electronic ballasts through 0-10V available signals according
to changes in daylight and lamp lumens. The DHTD
automatically dims lighting to maintain preset light level
conditions.
Key Features
• Low voltage daylight control
• Adaptive photoelectric light level sensor
• Fully adjustable time delay
•Programmable
• Compatible with new lighting systems
• Contemporary ceiling mount design
• UL and cUL listed
• Five-year warranty
Features and Benefits
Features
Adaptive photoelectric light level sensor
Benefits
Increases energy savings by dimming or turning off lights when
there is sufficient natural light.
Fully adjustable time delay
Minimizes nuisance switching
(e.g. cloudy areas would require a longer delay).
Programmable
Reduces energy usage by activating lights at predetermined
foot candle levels in specified areas only when artificial light
is necessary.
Applications
•Areas with natural illumination
•Entrance ways
•Windowed offices
•Breeze ways
•Task lighting
