Dimensions of drawing(mm) and Connection
1.Incorrect connection may lead to the damage of the sensor.ISN is positive when the IP flows in the direction of the arrow.
2.Dynamic performance (di/dt and response time)are best with a primary bar in the center of the through-hole.
3.When measuring currents less than 25A, multi-turn coils can be used in order to obtain the best accuracy, but considering the heat dissipation problem, the long-term working current of the sensor should be less than the rated input current.
