TBC25LAH 多量程闭环型霍尔电流传感器

TBC25LAH Multi-range Closed Loop Mode Hall Effect Current Sensor

TBC25LAH 多量程闭环型电流传感器的初、次级之间是绝缘的，可用于测量直流、交流和脉冲电流。

The TBC25LAH multi-range mode current sensor is a closed loop device based on the principle of the hall effect and null balance method. The output from the current sensor is the balancing current which is a perfect image of the primary current reduced by the number of secondary turns at any time. This current can be expressed as a voltage by passing it through a resister. It provides accurate electronic measurement of DC,AC or pulsed currents.
