The NIK 2306 is an intelligent three-phase smart energy meter engineered for both direct and transformer connections. Designed with modularity and scalability in mind, it features a replaceable communication module and supports a wide variety of interfaces including 4G/LTE, RS-485, PLC-G3, and M-Bus. The meter includes advanced features such as the “Last GASP” function for sending alerts during power loss, high-precision energy measurement (accuracy class 0.5s for transformer setups), remote firmware updates, and strong data encryption. Ideal for industrial and smart grid applications, NIK 2306 ensures reliable metering, communication, and control in demanding environments.
