First, a brief introduction

Factories, schools, street lights, water island of Pharos. Discount days up to the attendants to turn off the lights, turns the light on dark again. Often cause does not turn on the light or turn off the lights in a timely manner, it will not only waste of electricity, but also affect the work.

My factory according to all relevant information, the introduction of foreign advanced integrated circuits, and previously produced in the factory lamp switch based on the restructuring, a more practical value of street lamp automatic switch. The switches are not affected by seasonal weather effects, and features a reliable, sensitive and sold throughout the country, by the user's welcome.

Second, the working principle and structure

With delay circuit in the circuit, to prevent lightning by accident or flashlights, cars, and other light and optical head, deciduous flew low short block power of accidental errors of anti-jamming capability.

Street lamp automatic switch with photoelectric conversion device the optical head and manifold block, electronic components, do the relays, AC contactor form. Strong light during the day, light sensors current increases, the integrated circuit relay release lamp does not light, to dark one by one point in the evening, weakened due to light, light sensors low voltage relay sucks and shuts the lights on until the following morning, light strengthening integrated trigger automatic actions again, street fight.

Third, installation and use

(A) that will usurp automatically switches to install the lamp wires placed columns or where there is natural light, clean, timely automatic switching dust or wipe on a regular basis, so as not to affect the photovoltaic effect. Street lamp automatic switch terminal knob is for adjusting sensitivity, Shun, reverse adjustment, according to the local weather, needs to turn on the lights when it gets dark the relay sucks and shuts during the day when you need to turn off the lights relay release.

(Ii) automatic switch Terminal from left to right:

(1) power input

(2) for the central line shared

(3) for the power supply output

Four technical specification

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

2, contact capacity: 220V

3, relay contact: 1A
