The network consists of a mother controller, dual power controller, and automatic transfer switch

产品概述：
WQ7C is used for intelligent control of two incoming lines and one busbar in low-voltage power supply systems. Accurately measuring two three-phase voltages and making accurate judgments, thus achieving automatic switching between two incoming switches and a connecting switch in a three in two manner. It has functions such as precise measurement, intelligent control, anomaly detection, historical recording, reclosing, power-off and remote communication, and is widely used in power, communication, municipal and smart building scenarios.
