Data Concentrator Unit (DCU)
A DCU is usually installed in a sub-station. It is an intelligent device with built-in LPR modules to acquire data from Electronic Energy Meters or MIUs using AMR Software. Its’ in-built 2G/ 3G module then transmits data to the Data Acquisition Server Interfaced with Data Logger PC. 

A Meter Interface Unit (MIU) is connected to Electronic Energy Meters and enables wireless transmission of data from meters to DCUs. It eliminates conventional cabling requirements between meters and DCUs, thereby ensuring a quantum jump and data integrity of the system.
