Mains undervoltage and overvoltage protection circuit three
Source: InternetPublisher:通通 Keywords: Protection circuit overvoltage protection BSP Updated: 2020/04/26
It uses triode and triac V control. When the mains is under-voltage or over -voltage ,
V is turned off and the load power is cut off.
Adjust the potentiometers RPi and RPz to change the lower limit and upper limit setting values.
