July 2, 2004—The Watt Stopper’s new LightSaver LS-301 Dimming Photosensor offers an advance in daylight-responsive dimming with setup, commissioning, and user adjustments performed via handheld remote. These features simplify the setup process, eliminating adjustments at the photosensor and enabling the installer to observe the adjusted control response immediately.
The LS-301 is a ceiling-mount, low-voltage indoor photosensor accompanied by infrared handheld remote controls. The photosensor features an internal photocell that reports daylight and electric light illuminance via a spectral curve that matches the photopic curve. As the daylight increases, the lights dim down. The use of a sliding setpoint control algorithm ensures highly accurate dimming control.
The product works with 0-10 VDC electronic dimming ballasts. The LS-301 is suitable for a wide range of applications, including classrooms and offices of all types.
