Instructions for Use
1. Incorrect wiring may cause damage to the sensor. After the sensor is powered on, when the measured current passes through the direction of the sensor arrow, the in-phase current value can be measured at the output terminal.
2. The current input terminal of the sensor should be firmly and reliably soldered to the circuit board, and the width of the input terminal wire on the printed board should not be less than 1.5mm, the shorter the better. It is best to use double-sided epoxy board and double-sided wiring on the printed board to avoid overheating caused by long-term operation.
3. According to customer requirements, the original pins can be changed to four pins: 1, 3, and 6, 8.
