Details:
The Nero multi-tariff three-phase electronic meter is designed for metering active and reactive energy in forward and reverse directions in three-phase four-wire AC circuits with a frequency of 50 Hz.The meter is equipped with communication interfaces for operation in systems with remote sending of readings and possibility of simultaneous data collection using different communication technologies.
 
Features:
Sigfox, Lorawan, NB-IOT, Plug and Play & Nero UNB compatible
Active energy accuracy class 0.5S / 1; for reactive energy: 0.5 / 1;
Simultaneous collection of data via PLC and radio interfaces;
Communication interfaces: Radio (RF434 or RF868), GSM / LTE, RS-485, PLC, G3-PLC;
Removable GSM/LTE modem or DATD;
