Mains overvoltage and undervoltage alarm circuit
Source: InternetPublisher:aerobotics Keywords: Alarm circuit components logic levels Updated: 2020/05/20
Circuit working principle: lC1 is a special integrated circuit designed for temperature control
. Its characteristics are: ① Users can set the upper and lower temperature limits by themselves. ②When the temperature is higher than the upper limit
or lower than the lower limit, there is a corresponding logic level output. ③High reliability, low cost and few
peripheral components .
