1、 Overview
The rail mounted electric energy meter is suitable for installation in compact electric energy metering cabinets or cabinets. It adopts MODBUS interface, which facilitates the connection with PLC and other equipment to upload electric energy related data, and facilitates the automation management of electricity consumption. An automatic meter reading system can also be formed by communicating with a microcomputer through an RS485 communication interface. Rail mounted energy meters are the latest generation of miniaturized intelligent energy meters launched in recent years. This series of electric energy meters has the advantages of small size and easy installation, as well as extremely high accuracy and good anti electromagnetic interference performance, fully meeting the relevant technical requirements of level 1 and level 2 electronic energy meters in the national standards DL/T614-1997 and GB/T17215-2002. The model of the three-phase rail mounted electric energy meter is DTS2026-N, which adopts LCD display. The enhanced version can be set for clock, rate period, etc., and has pulse output function;
