Instructions
Primary sampling resistance R1: when testing the rated current, the accuracy of the sensor is the best; Therefore, when selecting the resistance value of resistance, select the resistance value of R1 as much as possible, just so that the primary current after rated voltage conversion is 10mA
For example, the measured rated voltage is VPN=250V
Measurement range (recommended): considering the resistance of the primary coil (in order to reduce the measurement deviation as much as possible, the resistance of the primary coil must be far less than R1) and insulation, the sensor is suitable for measuring the rated voltage of 10 ~ 500V;
Remarks:
When the measured current passes through the primary pin of the sensor, there is a corresponding voltage signal output at the output end;(Note: wrong wiring may damage the sensor)
