Overview
Overview: The three-phase four wire (rail type) electronic energy meter is a smart energy meter developed by our company using microelectronics technology to measure electrical energy. It adopts specialized large-scale integrated circuits and advanced processes such as digital sampling processing technology and SMT technology. Complies with the relevant technical requirements for Class 1 three-phase active energy meters in the national standard GB/T17215.321-2008; It has the characteristics of good reliability, small size, light weight, beautiful appearance, advanced technology, and 35mm DIN standard rail installation. It also has good resistance to electromagnetic interference, low energy consumption, high precision, high overload, high stability, anti-theft, and long life. It has infrared and RS485 communication interfaces, with optional communication protocols of 645 or MODBUS, and has the advantages of anti electricity theft and arbitrary installation location. Built in high-power magnetic holding relay enables remote opening and closing for cost control management.
