New 4000m long distance 220V high power water pump wireless remote control switch Manual wall | Инструменты

Scope of application: 220V household electric power, electric appliances with power less than 3000 watts can control its power supply and power off, such as: water pump, mud pump, motor, lamps, fans, fans, insecticides, sprayers, car washing machines, Electric bells...etc. Features: 1>. Long distance: It adopts imported UHF three-level signal to amplify the launching tube, which is farther away from the 3,000-meter remote control on the market. 4000 meters is the theoretical distance. The general open-air remote control distance is between 1000m and 3000m ( The environment is different, the distance is also different, the actual use depends on the size of the environmental disturbance), and the distance will be shortened in the case of obstacles. 2>. Switching power supply step-down circuit: using the switching power supply chip LNK304 produced by American POWER Company to control the power supply, quality assurance, stability and durability. 3>. Wide voltage: Suitable for voltage between AC85V-260V, ensuring long-term stable operation in circuits with different voltage environments. 4>. High power: Adopt Ningbo Songle 30A relay to ensure long-term stable control of high-power electrical appliances.No need to use AC contactor, directly control the water pump, motor, lamp, car washing machine and other electrical appliances within 3000W. 5>. High sensitivity: The signal receiving adopts the real superheterodyne RXB8 module, the sensitivity is -114dBm, the sensitivity and anti-interference ability are far beyond the super-regeneration on the supermarket surface and the ordinary superheterodyne module, the remote control distance is farther and more stable. 6>. Learning type code: You can learn the code with the same frequency remote control at will. (Don't worry if you lose the remote control during the process. Just buy a remote control and learn it. It is OK, no need to replace it, which greatly saves the user. cost). 7>. The operation is simpler: the remote control has 2 buttons, one button is on, and one button is off, which is convenient and easy to use.   8>. Do not interfere with each other: digital coding is used, and there is no mutual control phenomenon between the same model products of neighbors. (ie: multiple sets of the same model can be used in the same environment without mutual control.)
