TBC-LTHA系列*闭环型电流传感器的初、次级之间是*缘的,无位置误差,能真正测量分辨1000:1,用于精密测量直流、
交流和脉冲电流。
The TBC-LTHA Series current sensor is a closed loop device based on the measuring principle of the hall effect, with a galvanic isolation between primary and secondary circuit, the size of primary doesn’t affect test precision, no matter the location of primary in the hole of current sensor. It can really measure resolution 1000:1, it uses for precision measurement of DC, AC and pulse current.
