1.The primary mounting hole is Φ1.4mm
2.The secondary mounting hole is Φ1.0mm
1. Incorrect wiring may cause damage to the sensor. After the sensor is powered on, when the measured current passes through the arrow direction of the sensor, the in-phase current value can be measured at the output end.
2. Sensor current input welded to the circuit board should be solid and reliable, and the width of the input wire on the printed board is not less than 1.5mm, the shorter the better, the printed board is best to use double-sided epoxy board, and double-sided wiring, so as not to cause the board to heat for a long time.

Using Hall effect and open-loop measurement principle, after TRMS calculation, the measured current is converted into DC current or voltage output proportional to the primary current, and the current sensor can measure DC, AC, pulse and various irregular waveforms of current under the condition of electrical isolation. It has the characteristics of high accuracy, high linearity, high integration, small size, simple structure and long-term stability.
