        應用連接及說明Application connection and description



        1. 測試說明Test instructions

        通過測量流過RM 的測試電流Is,或者RM 兩端的電壓UR,可以得到原邊電流IP:

        By measuring the test current Is flowing through the RM, or the voltage UR at both ends of the RM , the original side current IP can be obtained:

        IP= KN *Is= KN * (UR/RM)

        2. 指示燈和指示信號說明Indication lights and indication signals

         

        在正常工作情況下,有效指示燈處于常亮狀態。如果指示燈熄滅,說明電流傳感器處于非零磁通狀態,如母線電流超過量程等。此時,傳感器內部進入掃描狀態,輸出電流不再與輸入電流信號等比例,一旦母線電流回落到量程之內,傳感器即恢復正常工作。有效指示信號與指示燈是同一信號驅動的,它為OD 門輸出形式,有效時輸出對應為低電平。

        Under normal working condition, the effective indicating lamp is working. If the indicator lights out,

        It indicates that the current sensor is in a non zero flux state,for example, bus current exceeds range.At this time, the sensor enters the scanning state, and the output current is no longer proportional to the input current signal. Once the bus current falls back within the range, the sensor will resume normal operation.The valid indicator signal and the indicator lamp are driven by the same signal. It is the output form of OD gate. When valid, the output corresponds to the low level.

         

         

        IS 在IP 按箭頭方向流動時,是正向的。

        IS is positive when IP flows in the direction of arrow.

        原邊導體溫度不能超過100℃。

        The temperature of the primary conductor should not exceed 100 C.

        此模塊為標準傳感器,對于特殊的應用請與我們聯系。

        This module is standard sensor.For special purposes, please contact us.

        我們保留對傳感器修改的權利,恕不另行通知。

        We reserve the right to modify the sensor without notice.

         

        安 全事項Security matters:

         

        1.       Attention should be paid to the bare conductive part of the terminal when wiring to prevent ESD impact as far as possible. It needs  professional construction experience engineers to wiring the product. The connecting wires of power supply, input and output must be connected correctly, and must not be dislocated or reversed, otherwise the product may be damaged.

        2.       There should be no conductive dust in the installation and use environment.

        3.       The potentiometer installed on the product is used for internal debugging and calibration of the company, and the user can not be adjusted.

        4.       Severe vibration or high temperature may also cause damage to products.Please pay attention to using environment.

        5.       Please pay attention to the danger of electric shock. After installation, the operator should not touch any bare conductive parts. When necessary, sensors can be protected, such as protective cover and so on.
