Leviton PCC1D-W Provolt Line Voltage Photocell, Ceiling Mount

By combining a 1-10V dimming photocell with the power of a Leviton power pack, the Leviton Provolt Line Voltage Photocell (Ceiling Mount) is an all-in-one mini daylight harvesting system - no separate power pack needed. The photocell includes two removable light pipes for either open or closed loop applications. It's an elegant solution to maximize natural light indoors (with the bonus of energy savings), while automatically adjusting your dimmable lamps and light fixtures as daylight levels change, always maintaining your Desired Light Level (DDL) for the room. The photocell controls a 1-10 VDC dimmable ballast (electronic or magnetic) or LED driver. For new construction or retrofitting, the photocell mounts to the ceiling with the included mounting plate. It auto-detects a momentary or maintained wall switch/station for manual override control. It uses 3 types of daylight harvesting applications: 1) Closed loop: Detects total photo-metric light from daylight or electric sources in the space. 2) Open loop: Detects daylight OR electric light only; requires manual calibration. 3) Adjustable daylight design levels: Normal (OFF) and Auto-Calibration.
