Data concentrator unit is a micro controller based device which has dual communication capabilities Viz. GPRS and LPR. DCU is designed to collect the data from Meter Interface Unit over Low Power Radio and transfer the data further to the central server using GPRS. It has been with in built power supply which can withstand surges upto 6 KV and also has rechargeable Li-ion battery. DCU can be configured from MDAM Software for data transfer schedules and schedules reading MIU. One DCU can handle upto 8 number of MIU's. DCU supports inboundoutbound and event based dialing.

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.

Electrical Power has become indispensable to human survival and progress. Increasing gap between demand and supply made every other nation explore ways and means to enhance Power Generation capabilities from both conventional and non-conventional means. Apart from efforts to meet growing demand, mounting AT&C losses in distribution is another challenge being faced by utilities world wide. Specifically developing countries owe to lack of proper energy accounting from infrastructural, technological shortfalls and manual interventions in energy billing. In the wake of technology upgradation and automation in the Energy Distribution, Automated Meter Reading (AMR) or Meter Data Acquisition and Management assumes importance in enabling the utilities to gather business and operational intelligence, through collection of base line data to analysis, monitor and manage operations in AT&C losses reduction
