Features:
The use of accumulator power causes the output voltage decreases,if the accumulator in low voltage for a long time,it will damaged.This suite can be used of testing 9V/12V accumulator output voltage,when accumulator in low voltage/under voltage,the red indicator lights up and the buzzer calls,which realized sound-light alarm,in order to achieve mastering accumulator discharging status.
1.Principle description
This suite has simple circuit and uses the LM358 chip,it used as voltage comparator.The comparison value is setted by potentiometer.When the input voltage is reduced to the setted value,the transistor turned on , LED lights, the buzzer calls.
2.Electrical Characteristics
Operating Voltage:9v/12v DC
Main chip:LM358
PCB size:32*26.7mm
