R718N360D Wireless 3-Phase Current Meter Interface

   

R718N360D, the three-phase current meter, is to detect the current of three-phase load. The device is compatible with the LoRaWan protocol and equipped with a wireless communication module to display the collected data in the gateway. The R718N3xxD is powered by DC and receives AC via current transformers (CTs). Through the copper wires, devices can be connected to CTs, which proportionally convert high-voltage current in the primary winding into the lower-value current in the second winding.

Current Measurement Range
and Accuracy

Current Transformer Specification:
R718N360D can be connected with CTs as long as the output current of the second winding does not exceed 1A. The measurement range of it is not limited, but the accuracy cannot be guaranteed.
In-Plant Testing and Measurement:
Using CT with the accuracy of 1% and maximum detection current of 600A, R718N360’s accuracy can be in the range of 1.5% when the current is in the range of 6A-600A. If it exceeds the range, the accuracy cannot be guaranteed, and it needs to be confirmed according to the actual measurement.
