Data Concentrator Unit (DCU)

image RF DCU Data Concentrator Unit

    Melange Systems Data Concentrator Unit (RF DCU) is an intelligent device gathers data from group of connected Smart Meters without any human intervention and uploads it to the remote server over a WAN. DCU also has capability to push energy meter data to the Head End Server System, in case of events like tamper .etc. These units are designed for the fixed RF mesh networks and available in IP65 enclosures suited for outdoor applications.
