Product Description

                           Smart Engonitoring AC Meter for Efficient Power Management
 
1.Product profile
The intelligent AC energy meter is developed based on the basic needs proposed by the company's customers, combined with the technical accumulation of the company's existing products. It is mainly used for monitoring and energy consumption measurement of basic parameters such as current and voltage of various electrical equipment. The product has two types: AC and DC. The DC type is used for measurement based on four DC output circuits using one voltage; The AC type is used for measuring three-phase AC electricity. The intelligent AC energy meter mentioned in this document refers to an AC type acquisition terminal. The product has 4G communication function and can be directly connected to the backend software for monitoring through 4G communication. It also has a human-machine interface for local operation.
Intelligent AC energy meters are mainly used in the field of electricity information collection for three-phase power networks with frequencies ranging from 45 to 65Hz. It can measure all electrical parameters in the power grid and exchange data with the upper computer through communication. Users can set the internal parameters of the product according to the actual situation on site, which is convenient to use, easy to operate, and has high accuracy; Widely used in various power IoT applications.
