Product Description：
The concentrator uses advanced measurement technology to ensure the accuracy and reliability of the data. Through wireless 4G/2G communication, the collected data is remotely transmitted to the management platform to a chieve remote monitoring and management. RF/RS485 meter collector, through RF wireless or RS485 wired communication mode to connect with the meter, according to the communication protocol supported by the meter, accurate real-time reading from the meter of various data, including cumulative electricity consumption (active power, reactive power), real-time voltage, real-time current, power factor and other information; It can copy the remote data of electric meter, reduce the errors that may occur in manual meter reading, and greatly improve the efficiency and real-time of data collection. It plays a key role in power data monitoring and management systems.
