            1. 测试说明Test instructions

            通过测量流过RM 的测试电流Is,或者RM 两端的电压UR,可以得到原边电流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. 指示灯和指示信号说明Indication lights and indication signals

             

            在正常工作情况下,有效指示灯处于常亮状态。如果指示灯熄灭,说明电流传感器处于非零磁通状态,如母线电流超过量程等。此时,传感器内部进入扫描状态,输出电流不再与输入电流信号等比例,一旦母线电流回落到量程之内,传感器即恢复正常工作。有效指示信号与指示灯是同一信号驱动的,它为OD 门输出形式,有效时输出对应为低电平。

            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 按箭头方向流动时,是正向的。

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

            原边导体温度不能超过100℃。

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

            安 全事项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.
