The CES allows the Heating Ventilation Air Conditioning Energy Management System (HVAC/EMS) to control area lighting by switching banks of lights on and off, or provide continuous signals to electronic dimming ballasts for fluorescent fixtures. (read more)

The MAS Series are light level sensors. As the light level increases during the day, the analog photodiode sensor responds with an increasing current. When the sensor saturates at its full scale output, it remains stable, until the light level drops and the sensor output begins to decrease. (read more)

The AC-PD is the most revolutionary photo-control of the 21st century and brings street lighting into the new millennium. One control fits any type of fixture, from lamps sizes of 70 watts to 500 watts and voltages up through 347VAC and it is compatible with any ballast type. (read more)
