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.

AWT100-AP/WFH is a Wi-Fi data conversion module compliant with the IEEE 802.11ah standard. It can operate in both STA mode and AP mode, enabling point-to-point or point-to-multipoint wireless data transmission through networking. Among the variants, the AWT100-AP/WFHEU European version supports the frequency range of 859 MHz to 894 MHz, while the AWT100-AP/WFHNA North American version supports 902 MHz to 928 MHz. Compared with 2.4 GHz Wi-Fi, it offers longer transmission distance. This module is suitable for applications such as wireless meter reading, building automation and security, and power load monitoring.
