A brief description

In general, factories, schools, streets of the street lights, the surface of the island's beacon lights. Folded by the officers off the lights, dark and then turn on the lights often cause not turn on the lights or turn off the lights, not only waste of electricity, jobs.

I plant according to various aspects of the relevant information, the introduction of foreign advanced integrated circuits, and in the factory before the production of street lights switch on the basis of restructuring a more practical value of the lights automatic switch. The switch from the weather season, Reliable, high sensitivity, popular throughout the country, welcomed by users.

Second, the working principle and structure

The circuit is equipped with a delay circuit, with the ability to prevent accidental lightning or flashlight, cars, and other light irradiation photoelectric head, leaves a low short-term occlusion of light power parts of the anti-jamming ability.

The street light automatic switch is composed of the photoelectric conversion device, namely photoelectric head and manifold, electronic component, executive relay and AC contactor.The light in daytime is strong, the current of photosensitive element increases, the relays of integrated circuit are released, Black to 11 degrees, due to weakened light, the photosensitive element voltage is low, the relay pull the street light until the next morning, the light to strengthen the integrated trigger automatically re-action, the lights off.

Third, the installation and use

(A), will install the automatic switch on the street lamp placed in the wire post or where there is natural light, pay attention to clean, timely or regularly wipe the dust of automatic switching head, so as not to affect the photoelectric conversion effect. Knob is to adjust the sensitivity, can be cis, inverse regulation, according to local days, so that the need to turn on the lights when the dark relay, the need to turn off the lights during the day when the relay release.

(B), automatic switching terminal from left to right:

(1) for the power input

(2) for the center line sharing

(3) for the power output

Fourth, technical conditions

1, the power supply voltage: AC 220V (such as with other power, please specify when ordering)

2, the contact capacity: A, 220V

3, the relay contacts: 1A

Fifth, the wiring diagram
