APM521 網(wǎng)絡(luò)電力儀表（以下簡稱儀表）按 IEC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(shí)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 IECinternational standards, featuring full electrical nt, energy statistics, power analysis, eventlogging functions, and network communication capabilities. It isprimarily used for comprehensive monitoring of power supply in power grids. This series of meters is e with DI/DOmodules and AO modules that offer a wealth of functions, allowingfor flexible implementation of full electrical measurementand monitoring of switch statuses in electrical circuits.
