NB-IoT Smart Energy Meter
Cellular-Powered Intelligence for Utility-Scale Efficiency
This advanced SOC single-chip processing system device is manufactured using SMT process technology, featuring simple circuitry, high reliability, and precise measurement accuracy. It performs active/reactive energy measurement along with current, voltage, power, and power factor measurements. With NB-IoT (narrowband Internet of Things) wireless communication, it offers excellent anti-interference capabilities, wide operating temperature range, and long-term stable performance.
Ideal for single-rate electricity pricing implementations, suitable for small/medium enterprises, commercial/residential users, secondary circuits, space-constrained single-phase equipment, photovoltaic bidirectional measurement, and charging pile applications. Enables remote centralized reading. Complies with GB/T17215.321 standard.
