Remarks:
1. All dimensions are in mm.
2. General tolerance ±1mm
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 are available.
