8. Application Instructions:
①The input coil between Pin 2 and Pin 4 must be connected in series 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 the output terminal. Pin7 is the adjusting terminal.
② While input AC current moving between 0~5A, output of 0~5V between Pin10 and Pin 8 is obtained and is linearly correspondent.
③Phase shift can be compensated by connecting a capacitor between Pin 7 and Pin10 and compensated to ≤15’ when choosing a capacitor of 0.033μF.
④Output voltage can be changed by connecting a resistor between Pin7 and Pin10 and it will be as bellow if the resistor connected is R and input current is 5A:
9.Attention:
① Pin 8 must be connected to ground, otherwise the accuracy will be compromised.
② If you want to convert the output AC signal to a DC signal, you can use the absolute value rectification method. Otherwise, the linear relationship will be disrupted due to the voltage drop across the diode.
③ Increasing the working voltage between Pin 6 and Pin 9 can extend the measuring range, whereas decreasing it will reduce the range.
④ If the output and input parameters do not suit your needs, we can customize them according to your specifications.
