Twist Lock Photocell Sensor, Auto On Off Photocell Sensor Switch, Dusk to Dawn Photocell Sensor for LED Area Light, LED Barn Light, Parking Lot Lights, Dusk to Dawn Light (UL Listed)

Specifications: Power voltage: 120-277V/AC Power frequency: 60Hz Ambient light: 2-50Lux Ratings: Tungsten: 120Vac, 60Hz, 1000W Standard Ballast: 120Vac, 60Hz, 1800VA Electronic Ballast: 120Vac, 60Hz, 8A Tungsten: 208-277Vac, 60Hz, 1000W Standard Ballast: 208-277Vac, 60Hz, 1800VA Electronic Ballast: 208-277Vac, 60Hz, 5A The product provide below advantages: ▶Multi-Volts Application ▶Fully Customization Available ▶Surge Arrester Built-In ▶Fail off modes ▶Zero - Crossing Switching (The advantage of this function is that when the photocell is turned on instantly, at the moment the voltage and current is zero, the reply operating at the optimal zero point, it avoids voltage and current damage to the relay, and greatly improve the lifetime of the relay and the entire products. It also solves the problem that the relay adhesion which causes the product lighting all the time!) Product Summary: The photocell control can open or close light according ambient-light, ambient-temperature and humidity cannot effect it. It's not only convenient but also practical, it can be used in the load of working all day and all night. for instant control road light, garden light etc. The photocell control is designed with microprocessor circuits with photodiode and a surge arrester (MOV) is provided. It's quicker response with time delay of 0-3 seconds offers easy-to-test feature. further, a preset 2-8 seconds time-delay might avoid mis-operation due to spotlight or lightning during the night time. the relay has sufficient work life of over 7300cycles. Use with TWIST-LOCK PHOTOCONTROL RECEPTACLE.(Conforms ANSI C136.41)
