Information
This information is part of the Modelica Standard Library maintained by the Modelica Association.
This is a comparator. Resistance R1 can be chosen, resistance R2 is defined by the desired reference voltage Vref (between Vn and Vp). The output switches between Vn for input voltage < Vref and Vp for input voltage > Vref.
