6．Outline Drawing, Installation Dimension and Function of Pins (Table below):

7．Models and Technical parameters as in the following table:

8．Application Instructions:

① 1-3 input Pins must be connected in parallel with the loop of the measured current circuit. Pin 6 connected to +B. Pin 9 connected to –B, Pin 8 connected to ground, Pin10 is output terminal. Pin 7 is a terminal for adjusting.

② While input AC moving between 0～Rated Voltage, the output between Pin 10 and Pin 8 is 0~5V and linearly correspondent.

③ Phase shift can be compensated by connecting a capacitor between Pin 7 and Pin 10 and compensated to ≤15’ when choosing a capacitor of 0.033μF

④ Output voltage can be changed by connecting a resistor between Pin 7 and Pin 10 and it will be as bellow if the resistor connected is R and input rated voltage:

9．Attention

① Pin 8 must be connected to ground, otherwise the accuracy will be influenced.

② If you want to change the output AC signal to a DC signal, you can apply the method of absolute value rectifying. Otherwise, the linear correspondence will be damaged due to the tube voltage drop of the diode.

③ Increasing the working voltage between Pin 6 and Pin 9 can extend the scope of measuring. Contrariwise, it will reduce the scope.

④ If the output and input parameters are not suitable for you, we can customize it according to your request.
