More Information
Summary:A DC power monitor includes a reference voltage and voltage dividers for obtaining voltages which are respectively above and below the reference level when the voltages being monitored are at their nominal value. Comparators compare the divided voltages with the reference and the comparator outputs are Anded and coupled through a flip flop to a bicolor LED which is one color when the voltages are in tolerance and another color when out of tolerance.
