使用说明 Remarks
1.当待测电流从传感器穿过 ,即可通过 RS485 获取当前被测电流数据。 2.可按用户需求定制不同额定输入电流和输出形式的传感器。
3.错误的接线可能导致传感器损坏。
4.本产品为弱电流传感器 ,内置精密磁性材料作为磁感应部件 ,容易受到振动和外界强磁场的干扰。建议用户使 用时 ,轻拿轻放 ,禁止摔碰。同时评估使用环境的干扰磁场强度。
1. When the current to be measured passes through the sensor, you can obtain the current measured through the RS485 port.
2. Sensors with different rated input current and output voltage can be customized according to user needs.
3. Incorrect cable connections may damage the sensor.
4. This product is a weak current sensor with built-in precision magnetic material as a magnetic induction component, which is easy to be disturbed by vibration and external strong magnetic field. It is recommended that users use it gently, and do not fall. At the same time, the interference magnetic field strength of the use environment is assessed.
