Introduction to the knowledge of solar street light controller

In this era of rapid development and a society that attaches great importance to environmental protection, solar street light has entered people's field of vision, and solar energy has been paid more and more attention by people. The combination of the two makes LED solar street light driven by the development of urbanization. It has also sprung up like mushrooms after a rain, but due to its high cost, many users prefer to choose low-cost, quality-deviation when choosing street lamps. Let's take a look at the special controller for solar street lights. First of all, the street light controller realizes the combination of working current and brightness requirements through electromagnetic, intelligent and data control. It mainly uses imported components to make the product work safer and provide users with safer and more efficient services. It can be divided into For waterproof controller and non-waterproof controller. The battery of the solar street light controller is 12V, and has the function of disconnecting and restoring the link. At the same time, considering the operating temperature characteristics of the battery, in different environments, the controller needs to have the function of temperature compensation, and set a reasonable charging voltage for the battery. , to prevent the capacity from being dropped prematurely or even scrapped due to overcharge or undercharge, so we specify a temperature coefficient of -3~7mv/℃ in the standard. In order to prevent the relay from being in the pull-in state when the controller is no-load, the logical relationship between the control element with a large driving current and the circuit operation must be considered, and the configuration current of each part of the circuit should be adjusted to the minimum value based on ensuring the normal use of the circuit. value, and when selecting the control element, the drive current is as small as possible. In addition, it is necessary to ensure that the charging and discharging voltage of the controller cannot exceed 5% of the rated voltage of the system.
