R718N3
Three-phase current monitoring on a battery: the R718N3 uses three solid-core current transformers, each rated to 50 A, and sends readings over LoRaWAN with better than ±1% accuracy from 300 mA to 50 A. The main unit only ever sees the CT secondary current, which keeps installation safe, and two AA-size lithium cells run for around 3.8 years at hourly reporting. The IP53 enclosure fixes by screw or magnet, and the CTs come on 900 mm leads; being solid-core, they are fitted with the conductor disconnected. It is suited to sub-metering three-phase plant such as chillers, air-handling units and distribution boards in commercial buildings, hotels and shopping centres.

Requires a LoRaWAN Gateway
R718N3 sends its data over LoRaWAN, so it needs a LoRaWAN Gateway in range. Works with any LoRaWAN Gateway, such as the UG65. If you already have a Gateway on site, you can skip this.
