Product Overview

Wireless lcd multifunction 4G WIFI rs485 DIN rail electric power meter

KPM37 Wireless 4G WIFI DIN rail multifunction electric IP power meter adopts DIN 35MM rail type installation structure and LCD display. It integrates three-phase electric parameter measurement, 2~31st harmonic analysis and time statistics. KPM37 default communication is Modbus-RTU by RS485 interface. WiFi, 4G, Lora communication are optional. The meter can also expand 2-way digital input and 2-way relay output, 4-way temperature measurement and 1 way residual current measurement. KPM37 has the advantages of small size, high accuracy, high reliability, easy installation, etc. It is mostly used for projects for system integration, wire line modification and in limited or inconvenient installation space, etc.
