TBC- BA/BS/BR 系列闭环型霍尔电流传感器
TBC- BA/BS/BR Series Closed Loop Mode Hall Effect Current Sensor
TBC-BA/BS/BR 系列闭环型霍尔电流传感器的初、次级之间是绝缘的，可用于测量直流、交流和脉冲电流。
The TBC-BA/BS/BR 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. It provides accurate electronic measurement of DC, AC or pulsed currents.
