Product parameters
Working voltage: 220V DC/12V DC 10A 50Hz/60Hz
Load power: incandescent lamp ≤1000W, energy-saving lamp, fluorescent lamp, exhaust fan ≤400W
Product features: automatic black on daylight
Features:
1. There is an automatic detection circuit for ambient illumination inside, which is automatically turned off during the day and automatically turned on at night.
2. It adopts a three-wire system and is compatible with various loads of resistive, inductive, and capacitive lamps.
3. The control object can be LED light, energy-saving light, fluorescent light, incandescent light, exhaust fan light, and the like.
4. It has a delay function when the environmental conditions change, and the delay time is 3-5S, which solves the problem of the screen flash of the load when the short-term environmental conditions change.
Application range:
Widely used in street lights, highways, factories, gardens, ports, airports, farms, parks, schools, and other places.
Package Included:
1x Light Switch Sensor Switch
Test:
1, the wiring method can not be wrong, according to our instructions.
2, in the daytime test open or close, please use opaque, wrapped in the switch, the switch lights up and works normally.
I. Brief description
General factory, school, street lights, and navigation lights on the island. During the day, the duty officer turns off the lights and turns on the lights in the dark. It often causes the switch to be turned off or turned off in time. This will not only waste power but also affect work.
Based on the relevant information in various aspects, and based on the previous experience of our factory, our factory has restructured a street lamp automatic switch with more practical value. The switch is not affected by the weather season, its function is reliable, its sensitivity is high, and it is sold well all over the world and is very popular among users.
Second, the working principle and structure
The circuit is equipped with a delay circuit, which has the anti-interference ability to prevent accidental lightning or manual flashlight, automobile, and other light illuminating the photoelectric head, and the falling leaves are low to temporarily block the optical power supply.
The street lamp automatic switch is composed of a power-off conversion device, that is, an electric power head integrated block, an electronic component, and an execution relay. During the daytime, the light is increased, the current of the photosensitive element is increased, the relay of the integrated circuit is released, and the street light is not bright. When the darkness reaches a certain level in the evening, the light generated by the photosensitive element is low due to the weakening of the light, and the relay light is bright until the next day. In the morning, the light enhances the integrated trigger to automatically act again, and the street light is off.
