Abstract
The single-phase charge-control smart energy meter adopts the most advanced energy meter ASIC, microprocessor materials, non-volatile memory, permanently stored information, wide-screen LCD and other advanced technologies. A set of high-accuracy, wide-load, high-sensitivity, low-power-consumption, which is used for measuring the rated frequency of single-phase power grid 50 / 60Hz, in AC active energy meters. This single-phase electricity meter integrates multiple functions in one to realize active and active measures for energy to achieve remote real-time voltage, current, neutral current, power, power factor, and the use of remote systems to achieve sales of electricity users Pre-emptive prepayment. It can flexibly set various functions: free electricity consumption, fault alarm, automatic power off, record opening, automatic meter reading.
