Automatic Sensor Switch Waterproof Photocell Street Light Switch 12V Photo Control Photo Sensor Switch

Product parameters:

1. Working voltage:12VDC 10A

2. Load power: Incandescent lamps ≤ 1000W, energy-saving lamps, fluorescent lamps, exhaust fans ≤ 400W

Product function: automatically open at night, automatically close at dawn

Features:

1. There is an automatic detection circuit for environmental illumination inside, which is automatically turned off during the day and automatically turned on at night.

2. It adopts three-wire system and is compatible with various loads of resistive, inductive and capacitive lamps.

3. The control objects can be LED lamps, energy-saving lamps, fluorescent lamps, incandescent lamps, exhaust fan lamps, etc.

4. It has a delay function when the environmental conditions change, and the delay time is 3-5S, which solves the problem of screen flickering of the load when the short-term environmental conditions change.

Application range:

Widely used in streetlights, highways, factories, gardens, ports, airports, farms, parks, schools and other places.

Test:

1. The wiring method can not be connected wrongly, connect according to our instructions.

2. Please use an opaque object to test on or off during the day, wrap it on the switch, and the switch lights up and works normally.

Product description:

General factory, school, street lights, beacon lights on water islands. During the day, the staff on duty will turn off the lights and turn them on again after dark. It often causes the lights to be switched on or off in time. This not only does not waste electricity, but also affects work.

According to the relevant information of various aspects and the past experience of our factory, our factory has remodeled a kind of automatic street light switch with practical value. The switch is not affected by the weather and season, and has reliable function and high sensitivity. It sells well all over the country and is well received by users.

Working principle and structure:

The circuit is equipped with a delay circuit, which has the anti-interference ability to prevent accidental lightning or manual torches, cars, and other lights from irradiating the photoelectric head, and the falling leaves fly low and temporarily block the wrong switching of the photoelectric power source.

The automatic street light switch is composed of a power-off conversion device, that is, a power-off switch head integrated block, electronic components, and an executive relay. During the day, the light is strong, and the current of the photosensitive element increases, so that the relay of the integrated circuit is released, and the street light does not light up. When it is dark to a certain extent in the evening, due to the weakening of the light, the voltage generated by the photosensitive element is low, and the relay picks up the street light until the next day. In the morning, the integrated trigger of light enhancement will automatically act again, and the street light will go out.
