CD60L Solar Battery Charger Controller 12V 24V 48V Charging Discharge Control Module Under Voltage Current Protector Board

"Charging mode IN By setting the upper limit voltage UP and the 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 starts charging the battery; when the battery voltage is more than or equal to the upper limit voltage UP, the relay disconnects to complete an automatic charging; when the relay turns on, IN flickers, indicating that it is charging. Discharge mode OUT By setting the upper limit voltage UP and the lower limit voltage dn; when the battery voltage is greater than or equal to the upper limit voltage UP, the relay turns on and starts discharging; when the battery voltage is less than or equal to the lower limit voltage dn, the relay turns off and completes an automatic discharging function; when the relay turns on, the OUT flickers, indicating that it is discharging. Note: This product is a simple voltage controller. It can turn on and off the output by relay. It only plays the role of switching, and can not change the voltage. Functional description: 1. Calculation of Voltage Percentage: Battery Voltage/(Upper Voltage-Lower Voltage) 2. Key function: Short press UP button, switch display% and time, long press 5 seconds switch mode, charging mode: IN, discharge mode: OUT SET key: Short Click to view the parameters currently set; Long press SET button to enter the parameter setting interface, set UP: voltage upper limit, dn: voltage lower limit, OP: turn-on time, dOP: delay turn-on time (0-999 seconds), FOP: forced turn-on time (0-10 seconds) in discharge mode. Short press DOWN button, turn off/turn on relay enable (emergency stop function) turn off, LCD display OFF, relay disconnect Long press DOWN button to set the status of LCD backlight L-P: OFF backlight constant brightness, ON: backlight automatically extinguishes after 5-10 minutes; after extinguishing, any key wakes up. THREE. Parameter Settings. (a) Enter the parameter setting interface by pressing the SET key for a long time; B) After entering the parameter setting interface, switch the setting parameters by pressing the SET key. C) After choosing parameters, it can be set by UP/DOWN key to support short press and long press. D) To set other parameters, repeat steps B and c; E) After all parameters are set, press SET key for a long time, exit and save; More details can see in pictures or contact us for help, Thanks^^"
