12V 24V 48V charge and discharge control module undervoltage current protection board CD60L solar cell charger controller

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;
