The indicating circuit of grid voltage fault discovery In the figure, the output terminal of the D/A converter DAC-08 is directly connected with the DC input voltage, which composes a typical A/D converter, but the input is an AC voltage here, which can detect and find out the grid voltage peeling or dropping, and the output digit can be displayed.
