4G wireless three-phase electronic energy meter

Product Overview

4G wireless three-phase electronic energy meterUsing industrial grade microprocessors as the core and external open CT, it supports power free installation and has the advantages of small size, high precision, and rich functions. It meets the installation requirements of low voltage cabinets and floor distribution boxes with strict space requirements and can support RS485 communication and wireless communication methods such as Lora, NB, 4G, wifi, etc. It is an ideal choice for data collection and analysis, as well as online monitoring, in electrical safety management, energy consumption management projects, environmental protection electricity supervision, and operation and maintenance projects.

System functions

The compound rate report mainly calculates the peak, off peak, off peak, and off peak electricity and electricity bills of a building. Select the project, branch, and date to be viewed, and choose one of the report types: "Day", "Month", or "Year". Click 'Search' to view the multiple rate report for this branch; Click 'Export' to export the table. As shown in the figure.Note: This report requires the measuring device to support the function of time period statistics.

Loss analysis can view the loss situation of each power branch, as shown in the figure.

The energy consumption report mainly compiles the daily, monthly, and annual energy consumption reports of buildings managed by the current logged in user. You can select daily, monthly, and annual reports for selected buildings based on different energy consumption classifications and export the tables. Select the category and date to be viewed, and choose one of the report types: "Day", "Month", or "Year". Click "Search" to view the energy consumption data of each building in this category; Click 'Export' to export the table. As shown in the figure. Support selecting project data to generate bar charts; Select the project you want to view and click on "Chart" to view the energy consumption chart of the project, as shown in the figure.

Wiring Diagram

three-phase four-wire

three-phase three-wire

Note:4G wireless three-phase electronic energy meterFour wiring methods can be used: three-phase four wire connection through current transformer, three-phase three wire connection through current transformer, three-phase four wire connection through voltage current transformer, and three-phase three wire connection through current voltage transformer. When using three-phase three wire connection, it is necessary to modify the wiring system of the instrument through buttons or corresponding debugging software.

When ADW300W is connected using the secondary mutual inductance method, the instrument's built-in secondary side transformer should be kept at a distance from the on-site primary side transformer to avoid interference.

Note: The ADW300W external transformer consists of two wires, red and white. The red wires are connected to instruments IA *, IB *, and IC *, while the white wires are connected to instruments IA, IB *, and IC; The ADW300-HJ external transformer consists of two wires, red and black. The red wires are connected to instruments IA *, IB *, and IC *, while the black wires are connected to instruments IA, IB *, and IC.
