Product Description

Product Parameters:Product model: XY-L10A,XY-L30AControl voltage: DC6~60vControl current: ≤10A/30A (as you choose)Control accuracy: 0.1VOutput type: direct outputVoltage error: ±0.1VUse range: various battery lithium batteriesAppearance size: 79*42MM6-60V any battery, lithium battery can be usedLCD display, battery voltage, charge percentage and charging time at a glanceThe function is very powerful, it can automatically charge control, can control the charging time, and can set and upload the corresponding parameters through the serial portParameter Settings：Press and hold the SET button to enter the parameter setting interface, the LCD will display SET;After entering the parameter setting interface, switch the set parameters by short pressing the SET button;After selecting the parameters, you can use the UP/DOWN button to set, support short press, long press (rapid increase or decrease);If you want to set other parameters, repeat steps b), c);After all the parameters are set, press and hold the SET button to exit and save;First, the function description:1. Automatic charging control function:By setting the upper limit voltage UP and the lower limit voltage dn; when the battery voltage ≤ the lower limit voltage dn, the relay is turned on, the charger starts to charge the battery; when the battery voltage ≥ the upper limit voltage UP, the relay is turned off, and an automatic charging is completed;2. Charging time control function:How to turn on time control?After entering the parameter setting, if the setting parameter OP is not 0, the time control function is enabled. The default parameter of the OP is: -----h, the time control function is not enabled by default;After the time control function is turned on (OP is not 0), when the battery voltage < lower limit voltage dn, the charger starts to charge the battery, and the system starts timing; during the timing, the battery voltage ≥ the upper limit voltage UP, the relay is turned off; if the battery voltage <Upper voltage, but the charging time OP time is up, the relay is off; if the OP time is up, the battery voltage is still <lower limit voltage dn, the relay remains on, the charging time control function is automatically turned off, and the H:ER flashes to remind the user, time The parameter setting is unreasonable; press any key to stop flashing;Note: Time format: 00:59 (00 for hours, 59 for minutes) The maximum time is 99:59, which is 100 hours.3. Serial data upload and parameter setting function:The system supports UART data upload and parameter setting function (TTL level);UART: 115200, 8, 1

Key function descriptionIn the running interface (main interface),Short press the SET button to display the currently set parameters;Short press the UP button to switch between display charging percentage and charging time;Short press the DOWN button to select the enable/disable relay enable. If the relay is enabled to turn off, ‘OFF’ will be displayed to remind you that the relay is disconnected;Press and hold the UP button to set the status of the LCD backlight (L-P), OFF: the backlight is always on, on: the backlight is automatically turned off after 5-10 minutes;Press and hold the SET button to enter the parameter settings.Fourth, the calculation of the voltage percentage: battery voltage / (upper limit voltage - lower limit voltage).Five, additional features:a) Charging time recording function: When the charging time control is not turned on, the product will record a complete time. When entering the time display interface, the charging time will flash; when the time display interface is exited or the next charging is turned on (the relay is turned on) ;b) Automatic parameter detection: When the parameter is set, when exiting, if the voltage lower limit dn ≥ upper limit voltage up, the system will flash “ERR” to indicate the alarm;c) Battery access detection: This product is attached to the battery. If the battery is not connected, the system will display “nbE” on the lower line to remind you; 6. Common fault analysisQ: How many V levels are suitable for use? How many V voltages does this module fit?A: This model is suitable for use in the lowest 6V, up to 60V voltage range. The maximum expenditure level is 48V. Because the 48V battery is fully charged at 60V, it will burn when it is high. If your battery is higher than 48V, please choose other models.Q: The relay is ringing after power-on! The indicator light flashes?Answer: This is because your charging current is too large or the battery capacity is too small, and the voltage upper limit is reached immediately upon power-on. When the relay is disconnected, the voltage drops rapidly to the lower voltage limit, and charging begins again. When you want to reduce the charging current, usually the charging current is 1 to 1.5 of the battery capacity, such as 20AH battery charging current is generally around 2-3A! Note that high current charging can cause the battery to heat up, aging, bulging or even exploding!Q: What control method? Can I cycle automatically? Can you use the side charge? Can you limit the flow?Answer: This is voltage control. For example, set the voltage lower limit of 12.0V, the voltage upper limit is 14.5V, and the voltage is charged to 14.5V. This voltage is cut off. The voltage is reduced to 12.0V. The relay is closed and begins to charge. The mode only turns off and on, can't limit the current, the charging current is completely dependent on your charger!Q: Can I charge a 24V battery by inputting 12V, or can I charge a 12V battery by inputting 48V?A: This is a simple voltage controller that only functions as a switch. It cannot be charged to charge the battery. So what kind of charger should you prepare for charging the battery? necessary!
