DC 12V 24V Lead-Acid Lithium Battery Discharge Controller Low Voltage Over-Discharge Protection Board with Alarmer 5-20S Delay
-
Description:
It is a battery charge controller.This module has a delayed alarm,which is to delay 5 to 20 seconds after the battery is under voltage.If the battery is still under voltage,the module will alarm and cut off the output at the same time,so as to avoid the battery voltage fluctuation when the high current load starts misoperation.
2.Feature:
1).It is simple and practical,has audible and visual alarm prompts,and has strong versatility,which can be said to be suitable for most loads.
2).It has a battery voltage output indicator and a battery under-voltage disconnect output indicator,through which the working status of the product can be seen.
3).It has sound and light alarm function.
4).Its versatility is strong.
5).It can pass a maximum current of 30A,which is suitable for most 12V batteries.
6).You can adjust the value of undervoltage protection yourself.
3.Parameter:
1).Product Name:Battery Charge Controller
2).Supply Voltage:DC 12V/24V
3).Main Chip:LM358
4).Static Power Consumption:12mA
5).Dynamic Power Consumption:100mA
6).Work Temperature:-25℃~85℃
7).Work Humidity:5%~95%RH
8).Size:70*49*25mm
4.Application:
1).Example 1:If the load is a motor,the voltage of the battery will fluctuate when it is started.Once the voltage fluctuates to the undervoltage value,the output will be disconnected and cause malfunction.This type of delay can be used,with a delay of 2 to 5 seconds.Enough to restore the battery voltage to a stable value.
2).Example 2:When the car is just started,the lights in the car will flash.It is also because the current is relatively large when starting and the battery voltage fluctuates.In this case,a delay can be used.The delay is 2 to 5 seconds,which is enough for The battery voltage is restored.
5.Indicator working mode:
1).When the battery voltage is normal,the "normal" indicator on the board lights up and the output is on;when the battery is over-discharged (less than 10.4V),the board will automatically cut off the battery output,and the "undervoltage" indicator lights up and The buzzer sounds and realizes the sound and light alarm,so as to realize the control of the battery discharge status,so as to prevent the battery from being over-discharged and damaging the battery.
6.Adjustment Method:
1).The undervoltage voltage of the 24V module is about 22V.
2).Assuming that the voltage of 10.5V needs to be set to disconnect,adjust the adjustable power supply to 10.5V,measure the voltage of the Zener tube D3,adjust the potentiometer and measure the voltage of the test point to be equal to the voltage of the Zener tube D3,and set it.
3).The same is true for 24V,but the voltage of the 24V regulator tube will be higher,and the adjustment method is the same.
4).You can adjust the value of the undervoltage protection by yourself,clockwise to increase the voltage value of the undervoltage,that is to say,adjust the potentiometer clockwise,the sensitivity of the module will increase,but do not adjust it when you adjust it,it is recommended to have a voltmeter When adjusting.
