The three-phase Smart Electricity Meters Smartico E307 9M is optimized for smart metering systems. It comes in many shapes and variants. Whether you need a meter with or without breaker, a DIN-rail variant, or a meter with or without different wireless data transmission (LoRaWAN/NB-IoT/GSM). The Smartico E307 is a true intelligent meter, able to store data in non-volatile memory and measure active/reactive energy in both consumed and delivered to the power grid. The main function is accuracy measure loop power grid parameters, including voltage, current, power, frequency, energy, demand, limits, total harmonic distortion, voltage, and current imbalance, and other parameters.
