main feature: 1. Using single-chip microcomputer and special software, special software based on expert control system is adopted to realize intelligent optimized SOC control. 2. The temperature compensation uses an external temperature sensor, which has higher control accuracy than the built-in humidity sensor. 3. With full charge, over discharge, electronic short circuit, overload protection, unique anti-reverse connection protection and other automatic controllers: the above protection will not damage any parts, do not burn insurance. 4. The series PWM charging main circuit is adopted, so that the voltage loss of the charging circuit is nearly half lower than that of the charging circuit using a diode, and the charging efficiency is 3% -6% higher than that of non-PWM, which increases the power consumption time and improves the charging after overdischarge recovery. The normal direct charge and floating charge automatic control methods make the system have a longer service life; meanwhile, it has high-precision temperature compensation. 5. Intuitive LED luminous tube indicates the current battery status, allowing users to understand the use status. 6. -grade control chips are used to normal operation in cold, high temperature, and humid environments; at the same time, crystal timing control is used for accurate timing control.7. Using more intuitive LED digital tube display settings, one-touch operation can complete all settings, and the timing time corresponds to the digital tube display number-corresponding, the display is more intuitive. 8. The use of advanced power technology greatly increases the effective power per unit area and the structure is more compact. 9. Built-in ultra-strong voltage correction program to the accuracy of voltage at all levels and control the accuracy of the charging and discharging process. 10. In response to the LED street load, a half-power adjustment function is added, so that the lamp can automatically switch to half-power energy-saving state when the lamp is normally working until the middle of the night, which greatly reduces the energy consumption of the load and prolongs the time of system work. 11. With constant current output function, it can directly drive the LED load, and can adjust the constant current output current with the load power, changing the way that the conventional LED needs to be equipped with a constant current source, which is more convenient to install and reserves more space. 12. Adopting large-diameter, large-interval terminal blocks, which can be installed with a maximum of 6mm2 conductors, with a conductor spacing of 9.5mm, which enhances the insulation performance and installation reliability, and is not easy to slip.
