TBC-EP3系列高精度霍尔电流传感器的初、次级之间是绝缘的,无位置误差,能真正测量分辨1000:1,用于三相精密测量直流、交流和脉冲电流。
The TBC-EP3 Series current sensor is a closed loop device based on the measuring principle of the hall effect and null balance method, with a galvanic isolation between primary and secondary circuit, the size of primary not affect test precision, no matter the location of primary in the hole of current sensor. It can really measure resolution 1000:1 and it uses for precision measurement of DC, AC and pulse current.
