Charging Discharge Voltage Monitor Test Relay Switch Control Module DC 12V K7N3: $8
When board connected the power supply, IN signal terminal connected the measured voltage, then display the measured voltage value;
Short press K1 can enter setting threshold voltage, 6 times for a cycle(former 3 times are for lower limit and the other 3 times are for upper limit);
When the measured voltage is lower than the lower limit or higher than upper limit value, the relay works and the buzzer alarms.
In the range of setting value, the relay stop working and the buzzer will not alarm.
