These transducers require an auxiliary power supply and offer a highly accurate method of measuring the phase angle of the input. They have a full four quadrant capability. The output is a linear function of the phase angle between the two inputs (which can be current or voltage), the circuit can also be used as power factor transducer only added a COS circuit.
Output amplifier provides constant voltage or current output. Output is unaffected by load resistance provided it is within the specified range.
