Description:As-20 type light-controlled street lamp automatic switch is a novel photoelectric switch designed and manufactured according to the photoelectric conversion characteristics of semiconductor components. It mainly consists of a sealed CDs photoresistor and an integrated circuit. At dusk and dawn, the opening and closing of street lamps can be automatically controlled according to the changes of natural light, thus achieving the purposes of automatic control of street lamps and energy conservation. It can be easily mounted on wood, metal and concrete poles with brackets and can work under any weather conditions. Because of its novel design, reliable installation, small size, light weight, convenient installation, long service life, low price and other advantages, it is widely used in street lamps, highways, factories, gardens, ports, airports, farms, parks, schools and other places.
Features:1. There is an automatic detection circuit for ambient illuminance inside, which is automatically closed during the day and opened at night.2. Three-wire system is adopted, which is compatible with various loads of resistive, inductive and capacitive lamps.3. The control object can be LED lamp, energy-saving lamp, fluorescent lamp, incandescent lamp, exhaust fan lamp, etc.4. It has the delay function when environmental conditions change.
Installation considerations:1. AC power supply connection, black line and white line of light control switch are connected to input power supply, and white line and red line are connected to load equipment.2. DC power supply connection, black line of light control switch is connected to (-) negative pole of input, white line is connected to (+) positive pole of input, white line is connected to (+) positive pole of load equipment, and red line is connected to (-) negative pole of load equipment.3. Please use opaque material to test on or off during the day, wrap it on the switch, and the switch lights up and works normally.4. Be careful not to install the device in a place with extremely dark day. Please install the device above the light. Do not install the device under the light to illuminate directly, which will cause non-stop switch action.
