三相电表的本质设计目的是为了测量电能消耗及其质量因数，同时提供防止篡改的手段。今天的智能电表可以通过数据集中器、家庭区域网、以及除燃气表和水表之外的家庭设备连接到广域网（WAN）和云。这使得自动抄表基础设施（AMI）能够帮助公用事业机构更好地管理客户服务，并鼓励消费者采用节能行为优化成本。
我们提供范围广泛的能耗计量集成电路、高性能STM32微控制器、安全元件、高效的交流-直流（AC-DC）转换器、以及经过现场验证的可编程电力线通信（PLC）解决方案，以支持各种专门开发的标准（包括G3-PLC、PRIME和Meters-and-More）、以及支持wM-Bus、LoRa和Sigfox低功耗广域网（LPWAN）协议的Sub-GHz无线连接解决方案。
此外，我们还提供全套硬件和软件评估和开发工具（包括参考设计），帮助开发精确、可靠的智能电表。
