Nero - Multi Protocol - Single Phase Smart IOT Electricity Meter

Sales Tax Included


The intelligent retro-style multi-tariff single phase electronic meter combines from one to several communication
interfaces and allows the utilities to receive the readings and other data about active and reactive energy, generation and
consumption, voltage quality, tampering incidents, magnet exposure and etc. remotely.


Available communication interfaces include G3-PLC, NERO-PLC, Radio (RF433 or RF868), LTE/GPRS, RS-485, optical port.
