Battery Charger Control Module Digital Full Power Off Overcharge Protection, 501 Original

Feature:1. Any 6-60V battery, lithium battery can be used.2. LCD display, battery voltage, charging percentage and charging time at a glance.3. The function is very powerful. It can automatically charge and control charging time. It can set and upload corresponding parameters through serial port.Function:1. Automatic charging control function: By setting up upper limit voltage UP and lower limit voltage dn. When the battery voltage is less than or equal to the lower limit voltage dn, the relay turns on and the charger begins to charge the battery. When the battery voltage is more than or equal to the upper limit voltage UP, the relay is disconnected to complete an automatic charging.2. Charging time control function:A. How to turn on the time control function: After entering the parameter setting, if the setting parameter OP is not 0, the time control function will be turned on. The default parameter of OP is: --- h, the time control function will not be turned on by default.B. After opening the time control function (OP is not 0), when the battery voltage is less than the lower limit voltage dn, the charger starts charging the battery and the system starts timing. During the time period, the battery voltage is greater than the upper limit voltage UP, and the relay is disconnected.C. If the battery voltage is less than the upper limit voltage, but the charging time OP time is up, the relay is disconnected; if the OP time is up, the battery voltage is still less than the lower limit voltage dn. D. The relay keeps on, automatically closes the charging time control function, and flickers to show H:ER to remind users that the setting of time parameters is unreasonable; press any key to stop flickering.E. Note: Time format: 00:59 (00 for hours, 59 for minutes) the longest time is 99:59, that is, 100 hours.3. Serial port data upload and parameter setting function:A. The system supports UART data upload and parameter setting (TTL level).B. UART: 115200, 8, 1C. Command functionD. On relay enabled to turn onE. Off relay enabled to shutdownF. Start: starts the data reporting functionG. Stop: Stops Data ReportingH. Read Gets System ParametersI. Dw10.0 Sets Lower Limit VoltageJ. Up20.0 Setting Upper Voltage LimitK.

By long pressing the SET key for a long time and entering the parameter setting interface, the liquid crystal will display the SET.2. After entering the parameter setting interface, the set parameters are switched by pressing the SET key.3. After choosing the parameters, it can be set by UP/DOWN key to support short press and long press (fast increase or decrease).4. To set other parameters, repeat steps 2 and 3.5. After all parameters are set, press SET key for a long time, exit and save.Key Function Description:In the running interface (main interface)1. Short press SET button to display current setting parameters.2. Short press UP button, switch to show charging percentage and charging time.3. Short press DOWN button and choose to turn on/off relay enablement. If the relay enabled to turn off, it will display'OFF'to remind and the relay will be disconnected.4. Long press UP button to set the state of LCD backlight (L-P), OFF: backlight is always bright, on: backlight is automatically extinguished after 5-10 minutes.5. Long press SET key to enter parameter setting.Note: Please allow 1-3cm differs due to manual measurement.Due to the different display and different light, the picture may not show the actual color of the item.
