Application of Acrel Programmable Power Meter in Lao PDR

Background

This article introduces the application of the multi-function energy meter in a project in Lao PDR. AMC series AC multi-function meter is a smart meter designed for power monitoring needs of power systems, industrial and mining enterprises, utilities, and intelligent buildings.

Project Overview

A project in Lao PDR required a batch of multi-function and programmable power meters. After comparing various aspects, Denmark customers thought that our AMC series programmable power meters are rich in functions, easy to install, and cost-effective, so they decided to use our power meters.

Product presentation

AMC series meters integrate the measurement of full-electric parameters, such as single-phase or three-phase current, voltage, active power, reactive power, apparent power, frequency, power factor. It also has functions of energy statistics, event records, harmonic measurement and network communications.
