Introduction - netvox R718NL3 User Manual

1. Introduction

The R718NL3 series is a Light Sensor and 3-Phase Current Meter device for Netvox ClassA type devices based on the
LoRaWAN open protocol and is compatible with the LoRaWAN protocol. R718NL3 series have different measuring range for
different variety of CT.
It is divided into:
R718NL3 Wireless Light Sensor and 3-Phase Current Meter with 3 x 50A Solid Core CT
(Range:100mA-50A , Accuracy ±1% within 300mA~50A)
R718NL37 Wireless Light Sensor and 3-Phase Current Meter with 3 x 75A Clamp-On CT
(Range: 100mA -75A ±1%, Accuracy ±1% within 300mA~50A)
R718NL315 Wireless Light Sensor and 3-Phase Current Meter with 3 x 150A Clamp-On CT (Range:1A-150A ±1%)
R718NL325 Wireless Light Sensor and 3-Phase Current Meter with 3 x 250A Clamp-On CT (Range:1A-250A ±1%)
R718NL363 Wireless Light Sensor and 3-Phase Current Meter with 3 x630A Clamp-On CT (Range:10A-630A ±1%)
* When the current of the device that is 75A or below is less than 100mA, the current is reported as 0.
When the current of the device that is above 75A is less than 1A, the current is reported as 0.
LoRa Wireless Technology
LoRa is a wireless communication technology famous for its long-distance transmission and low power consumption. Compared
with other communication methods, LoRa spread spectrum modulation technique greatly extend the communication distance. It
can be widely used in any use case that requires long-distance and low-data wireless communications. For example, automatic
meter reading, building automation equipment, wireless security systems, industrial monitoring. It has features like small size,
low power consumption, long transmission distance, strong anti-interference ability and so on.
LoRaWAN
LoRaWAN uses LoRa technology to define end-to-end standard specifications to ensure interoperability between devices and
gateways from different manufacturers.
