UL 認(rèn)證光伏系統(tǒng)電力儀表以太網(wǎng)通訊

1 概述

APM521 UL 認(rèn)證光伏系統(tǒng)電力儀表以太網(wǎng)通訊（以下簡稱儀表）按IEC國際標(biāo)準(zhǔn)設(shè)計，具有全電量測量、電能統(tǒng)計、電能質(zhì)量分析事件記錄功能及網(wǎng)絡(luò)通訊等功能，主要用于電網(wǎng)供電質(zhì)量的綜合監(jiān)控。該系列儀表配有功能豐富的DI/DO模塊、AO模塊，可以靈活實現(xiàn)電氣回路全電量測量及開關(guān)狀態(tài)監(jiān)控。

The APM521 network power meter (hereinafter referred to as the meter) is designed according to IEC international standards, featuring full electrical quantity measurement, energy statistics, power quality analysis, event logging functions, and network communication capabilities. It is primarily used for comprehensive monitoring of power supply quality in power grids. This series of meters is equipped with DI/DO modules and AO modules that offer a wealth of functions, allowing for flexible implementation of full electrical quantity measurement and monitoring of switch statuses in electrical circuits.
