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.

 Note:

1 If the user needs other special calibration, please indicate the parameter value in the contract.

2 power factor input, output value conversion:

     y = a1cosф+b1(ф:0 to 60°)

     y = a2cosф+b2(ф:0~-60°)

In the above formula: y is the output of the power factor transducer, and y, a, b should be selected according to the different output modes of the powe
