30A Battery battery charging control module Full power off DC voltage protection undervoltage loss protector
Charge mode IN
By setting the 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 conducts and the charger starts to charge the battery. When the battery voltage is greater than or equal to the upper limit voltage UP, the relay is disconnected and an automatic charging is completed; The relay is on and IN blinks, indicating that it is charging.
 
Discharge mode OUT
By setting the upper limit voltage UP and lower limit voltage DN; When the battery voltage is greater than or equal to the upper limit voltage UP, the relay conducts and begins to discharge; When the battery voltage is less than or equal to the lower limit voltage DN, the relay is disconnected and an automatic discharge function is completed. If the relay is on and OUT blinks, it indicates that it is discharging.
 
Note: this product is a simple voltage controller, through the relay to open and shut off the output, only play the role of switching, not voltage change.
Function description:
1. Voltage percentage calculation: battery voltage/(upper voltage - lower voltage)
2. Key functions:
UP button: short press to switch display % and time, long press for 5 seconds to switch mode, charge mode: IN, discharge mode: OUT
SET key: Press to view the currently SET parameters. Hold down the SET button to enter the parameter setting interface. SET UP: upper voltage limit, DN: lower voltage limit, OP: on-time, dOP: delayed on-time (0-999 seconds), and FOP: strong guidance on-time (0-10 seconds) in discharge mode.
DOWN button: press the button to close/open the relay to enable (emergency stop function). After the relay is closed, the LCD displays OFF and the relay is disconnected
Long press DOWN button to set the state of LCD backlight L-P:OFF backlight is ON, ON: backlight will automatically go out after 5-10 minutes; After off any key to wake up.
3. Set parameters
A. Hold down SET to enter the parameter setting screen.
B. On the parameter setting screen, press SET to switch the SET parameters.
C. After parameters are selected, you can use the UP/DOWN key to set parameters. You can press and hold DOWN the key.
D. Repeat steps b) and c) to set other parameters.
E. After setting all parameters, hold down the SET key to exit and save the Settings.
 
3.1 Charge/discharge time control function
When the time parameter OP is set to non-zero, the charge/discharge time control is started. When the relay conducts to open a charge/discharge, start timing; When the timing is complete, the relay is automatically disconnected to complete a charge/discharge process; If the timing is complete, the detection voltage < the lower limit voltage DN in charging mode or the detection voltage > the upper limit voltage UP in discharge mode will automatically turn off the charge time control function, and the blinking display H:ER will remind the user that the time parameter is not set properly. Press any key to stop blinking;
In the case of no charge/discharge time control, the product will record a complete time, when entering the time display interface, flashing display charging time; Clear it when you exit the time display interface or the next charging start (relay conduction);
3.2 Automatic parameter detection:
When the parameters are set and exit, if the lower voltage dn is greater than or equal to the upper voltage UP, the system will blink "ERR" to remind.
3.3 Delay conduction function dOP(0~999 seconds):
The interval between completing a charge/discharge and opening again;
3.4 Forced start time of discharge conductance FOP(0~10S):
After the relay conduction condition is satisfied, the relay strong guidance pass (0~10S), and the battery voltage is tested again; This function is mainly for the discharge function. Some test loads will momentarily pull down to the lower limit voltage at the conduction moment, and the relay will be mistakenly triggered to disconnect and the normal discharge process cannot be carried out.
 
Common fault analysis
Q: What V level is suitable for use? What V voltage is suitable for this product?
Answer: this model is suitable for the use of the lowest 6V, the highest 60V voltage range, the maximum expenditure level 48V, because 48V battery is full of 60V, the higher it will burn, if your battery is higher than 48V, please choose other models.
Q: The relay snaps after power-on!
A: This is due to your charging current is too big or the battery capacity is too small to cause a immediately reaches the upper limit of voltage, electric relay disconnect, disconnect, voltage lower limit, voltage and quickly fell to start charging and cycle cycle, at this point you have to reduce the charging current and charging current is usually battery capacity of one over ten to 1.5, Such as 20AH battery charging current is generally about 2-3A! Note that high current charging will cause battery heating, accelerated aging, swelling and even explosion!
Q: What controls? Can automatic cycle charge? Can you charge it while using it? Can you limit the current?
Answer: This is voltage control. For example, set the lower voltage limit of 12.0V and the upper voltage limit of 14.5V. When the voltage reaches the value of 14.5V, the power will be off. Can be used while charging, voltage control mode only to turn off and open, can not limit the current, charging current completely depends on your charger!
Q: can I charge a 24V battery with 12V input, or can I charge a 12V battery with 48V input?
Answer: this is a simple voltage controller, only play a switch role, can not change the voltage to charge the battery, so you want to charge the battery to prepare what kind of charger! A must!
