The NIK 2300 is an advanced three-phase smart energy meter designed for both direct and transformer connections, supporting a wide voltage range and high-accuracy energy measurements. Available in two design variants, this model can measure both active and reactive energy with exceptional precision (accuracy class 0.5s for transformer type). Equipped with modern communication interfaces, optical port, configurable RESET button, and DLMS protocol support, the NIK 2300 offers seamless AMI integration. Its robust tamper protection, built-in disconnector, harmonic monitoring, and encrypted data transmission make it ideal for industrial and utility-scale applications.
