The traditional rain control switch is huge in size, very inconvenient to install and use, high in manufacturing cost, and difficult to promote. Our factory introduces foreign advanced integrated circuits and foreign advanced shapes according to relevant information in various aspects, and produces low-voltage electrical switches before the factory. On the basis of this, a more practical rain control automatic switch was remade. The switch is economical, not affected by the weather season, reliable in function and high in sensitivity. It is sold throughout the country and Southeast Asia, Europe, America and other countries and regions, and is welcomed by users.
Rated current: 10A adopts three-wire system, internally controlled by relays, compatible with various loads such as resistive, inductive and capacitive. (If the current exceeds 10A, please expand the capacity with the corresponding AC contactor)
Rated voltage: AC 90V / 260V AC / 220V AC / 110V DC / 12V
Working temperature: -40 ℃ to + 70 ℃ (-40F to + 158F)
Switch power consumption: <0.1W
Use: When it rains, when rain drops drip on the rain control probe, the switch will automatically cut off the power. When the rain on the rain control probe dries, the switch will automatically recover without manual operation. It is very convenient to use and install.
Working principle and structure
The rain control automatic switch is composed of a rain control probe, an integrated block, electronic components, and an execution relay. When it rains, when rain drops drop on the rain control probe, it will cause the short circuit of the adjacent two poles on the rain control probe, which will release the integrated circuit control relay. Damaged, when the rain stopped for a period of time, the rain on the rain control probe dried up, the adjacent two poles on the rain control probe returned to the open state, the switch automatically turned on the power, and the electrical equipment could work normally without manual operation.
The circuit is equipped with a delay circuit, which has the anti-interference ability to prevent accidental water droplets from causing accidental opening and closing.
Installation and use matters needing attention:
1) During the installation of the rain control probe, pay attention to the copper foil side of the probe facing upwards, and at the same time, install it in an outdoor unobstructed place, to ensure that rain drops on the probe when it rains;
2) After using for a period of time, the copper foil part of the probe will oxidize, which will affect the sensitivity of the switch. At this time, wipe it with a cloth or fine sandpaper to remove the oxide layer on the copper foil;
3) In general use, the switch is installed indoors, you only need to install the probe outdoors. If you need to install the switch outdoors, you should pay attention to the blue part of the switch facing up. Rainproof
Automatically switch the white and black wires to the power supply and the white and red wires to the load.
