The NIK 2116 is a high-end single-phase smart energy meter designed for accurate measurement, intelligent communication, and advanced grid functions. With support for active and reactive energy tracking, STS-based prepayment, DLMS communication protocol, and modern encryption for secure data transmission, this device is tailored for high-reliability smart metering applications. The model includes a replaceable communication module, a disconnector, a transparent housing, and tamper sensors. The “Last GASP” function enables event signaling at the moment of power loss—crucial for uninterrupted service monitoring in advanced AMI systems.
