TBC-LTHA 系列高精度闭环型霍尔电流传感器
TBC-LTHA Series High Precision Closed Loop Mode Hall Effect Current Sensor
TBC-LTHA 系列高精度闭环型电流传感器的初、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.
