Product Details

1 Product Overview

SC-GP-EM4G wireless energy monitoring meter is an intelligent power parameter monitoring device launched by Shanghai DAQ IoT Technology Co., Ltd., supporting transmission modes such as 4G/WiFi/LoRa. It can monitor the line voltage and current of single-phase and three-phase equipment, and can calculate active power, apparent power, power factor, operating frequency and active energy. It monitors the operating and power consumption conditions of single-phase and three-phase electrical equipment in real time, ensuring the safety of electrical equipment and enabling unattended monitoring. When combined with relay control devices, it can automatically cut off the power supply in case of overvoltage or overcurrent. It is widely used in scenarios such as environmental protection power monitoring and monitoring of factory equipment working status.
