APM520 Multifunktionales Energiezähler

APM520 Multifunctional Energy Meter

The APM5 series network power meter (hereinafter referred to as the meter) is designed according to international IEC standards and features full power measurement, power statistics, power quality analysis (including harmonics, interharmonics, and flicker), fault recording (including temporary voltage spikes and dips, inrush current, and other recordings), event recording, network communication, and other functions. It is primarily used for comprehensive power quality monitoring in electrical networks. This series of meters is equipped with feature-rich DI/DO modules, AO modules, wireless communication modules, and leakage temperature measurement modules, enabling flexible implementation of full electrical circuit power measurement and switching state monitoring.
