Overview

Overview: The single-phase rail type multifunctional electric energy meter is a new generation of miniature multifunctional programmable power instrument launched by our company. It adopts a 35mm standard rail type installation and has the advantages of small size, high accuracy, good reliability, and easy installation. Its performance indicators meet the technical requirements of GB/T17215 and DL/T614 for electric energy meters. It has a remote RS-485 digital communication interface, adopts DL/T645-2007 protocol, supports MODBUS RTU communication protocol and data exchange with the upper computer, and can complete energy measurement, power measurement, data display, and remote transmission. It is mainly used for intelligent buildings, internal energy measurement of enterprises, and management assessment.
