产品详情

　　TBC-LAH系列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 TBC-LAH 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.

　　使用说明 Directions for use

　　1. 当待测电流从传感器穿过，即可在输出端测得电压大小。(注意：错误的接线可能导致传感器损坏)

　　When the current will be measured goes through a sensor ,the voltage will be measured at the output end.

　　(Note: The false wiring may result in the damage of the sensor).

　　2. 可按用户需求定制不同额定输入电流和输出电压的传感器。

　　Custom design in the different rated input current and the output voltage available.
