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.

ADL3000-E three phase electric meter is designed for three phase energy measurement on low voltage system and EV charging pile. The meter meet the related technical requirements of electronic meter in the IEC62053-21、IEC62053-22 standards.

APM5 series network power meter is designed according to IEC international standards, with full power measurement, power statistics, power quality analysis (including harmonics, interharmonics, flicker), fault recording function (including voltage temporary rise and fall interrupt, inrush current and other records), event recording function and network communication and other functions.

The ADF400L series multi-user electric energy meter can achieve up to 12 three-phase or 36 single-phase direct access measurement or 12 three-phase mutual inductor access measurement, a hybrid of direct access and mutual inductor access through module combination measurement method.
