  • 1. Brief Introduction 

    EM519037 is a three-phase four-module electronic energy meter with IR and RS485 communication (MODBUS protocol, RTU method), It can be set through RS485 communication to set the meter as 2 single-phase meters; A(L1) and B(L2) a single-phase meter; C(L3) and N a single-phase meter ; LCD display, metering, tariff, event, and alarm can all be separated separately. It has the characteristics of good reliability, small size, light weight, beautiful appearance and convenient installation.
