1、overview

LORASingle phase intelligent energy meters use dedicated large-scale integrated circuits,It has the characteristics of high precision, high reliability, high overload, low power consumption, small size, and light weight, and can be used as a remote collection and measurement terminal.The available reference frequency for measurement is50Hz or 60Hz single-phase AC active power,useRS485 communication.

The electric energy meter is designed for fixed installation indoors, with an ambient temperature of-25 ℃~+70 ℃, with a relative temperature not exceeding 80%.

This table can directly and accurately measurePower consumptionAt the same time, it hasLora has wireless transparent communication function, which can achieve remote meter reading and remote control. The communication protocol supports DL/T645-2007 "Multi functional Meter Communication Protocol", and all performance indicators meet the requirements of DL/T614 "Multi functional Energy Meter" or MODBUS-RTU communication protocol.
