3.1 Detailed product function

   1. LCD screen display
       Under normal mode, the uplink of the LCD screen shows the input voltage and operating temperature; the downlink shows the real -time current, power, capacity, and discharge time.
       In the protection mode, the LCD screen shows the protection code.
       In the setting mode, the LCD screen displays each settings parameter code and parameter threshold.
   2. Sound and light alarm
     When the output of the voltage current is turned on, the RUN indicator light is often on, and the bee tweee does not sound; when it is turned off, the RUN indicator is not bright, and the bee twiser does not sound.After entering the protection mode, the bee twitters of the bee twitter called the police, and the Run indicator flickered.
   3. Automatic statistics of the charging and discharge capacity and time. As long as the output (Run indicator light is always on), start statistics, turn off the output (the Run indicator is not bright), stop the statistics, the power loss statistics are automatically cleared, and the display capacity and time are displayed.During the interface, long press the button—You can clear the corresponding data.Before starting statistics, please clear the statistics.The maximum discharge capacity (OAH) and maximum discharge time (OHP) can be set to open or close (default shutdown) in the setting mode. After opening, you can set the threshold size, exceed the threshold, the output is automatically closed, and the beeurizer alarm to achieve no realization.Human -to -person battery is charged and discharged.
   4. By setting the appropriate overvoltage protection threshold and the underwriting pressure protection threshold, the battery can be overcharged and overlap.For more detailed operation, please refer to the example of product application.
   5. Perfect software and hardware protection mechanism, and software protection thresholds can be adjusted.After the software is protected, the output is turned off.
     Hardware protection:
     The module input port has anti -anti -connection protection, and the counter -connection is not burned.
     Software protection:
   OVP overvoltage protection (default 38V, you can set itself. After the overvoltage protection, the Run indicator lights flickered, and the liquid crystal interface displays OVP. In the battery charging, set the appropriate threshold to effectively prevent the battery from being charged);
   OCP overcurrent protection (default 5.5A, you can set it by yourself, after the overcurrent protection, the Run indicator flickering, LCD display OCP);
   OPP is too power protection (the default is 200W, you can set it by yourself. After the power protection, the RUN indicator flickered, the LCD display OPP);

   OTP over -temperature protection (default 80 ° C, you can set it by yourself. After the temperature is protected, the Run indicator lights flickering, the LCD display OTP);      
     LVP under pressure protection (default 4.8V, you can set it by yourself. After the underwriting protection, the Run indicator lights, LCD display LVP, and set the appropriate LVP in battery discharge testing and other applications to effectively prevent the battery from excessive discharge, so as not to damage the battery.
     6. The voltage current output is turned on by default.
     7. All parameters support the power loss storage.
