R718N360 Wireless 3-Phase Current Meter Interface

R718N360 Wireless 3-Phase Current Meter Interface

The NETVOX wireless three-phase current interface which can detect the current can be connected with the different CTs by the user. The device is compatible with the LoRaWAN protocol and integrates a chip module that conforms to the LoRaWAN wireless protocol to display the collected data in the gateway. The device is powered by battery and obtains the load AC current value through the current transformer.

Electric

Power Supply: 2×3.6V ER14505 lithium batteries

Operating Voltage: 3.1v to 3.65

Standby Current: <25uA

Wakeup Current: 7mA

Receiving Current (max): 11mA @3.3V

Transmitting Current (max): 120mA/3.3V

Battery Voltage Accuracy: ±0.1V

Low Voltage Threshold: 3.2V

Current Measurement Range: It is recommended that the primary side current be at most 600A,and the secondary side current of the current transformer is at most 1A. If the accuracy of CT current transformer is 1%, the accuracy of R718N360 is 1.5%. (According to the current ratio configuration of the current transformer, as long as the secondary side current of the current transformer specification is at most 1A, the current transformer can be connected to R718N360 theoretically.)
