Description
Overview
A NWE DCU is an intelligent device with built-in LPR modules to acquire data from Electronic Energy Meters or Meter Interface Units (MIUs) using AMR Software. Its in-built 2G/ 3G module then transmits data to the Data Acquisition Server Interfaced with Data Logger PC. A NWE DCU is usually installed in a sub-station. A MIU is connected to Electronic Energy Meters and enables wireless transmission of data from meters to NWE DCUs. It eliminates conventional cabling requirements between meters and NWE DCUs, thereby ensuring a quantum jump and data integrity of the system.
Key Features
- Compact and Easy to install
- Supports any of the communication technologies (2G/ 3G).
- Supports MIOS compliant/ Modbus / IEC 62056-21/ DLMS Meters.
- IP (Internet Protocol)-based Communication, enabling simultaneous data access from hundreds of AMRs/ DCUs. Secure and reliable data transfer through VPN.
- Can be made a wireless system with the use of MIUs
- Real-time Tamper Alerts/ Event notifications to Data Centre/ Mobile phones of officials in the field through SMS.
- Online monitoring of vital instantaneous parameters such as voltages, currents, energies, power, power factors, power quality etc.
- Power Outage Management
- Remotely configurable and feasible firmware upgradation
- In-built universal power supply (1-Phase/3-Phase) with battery backup (optional)
- GPS time synchronization from central server for effective energy audit
- Two-way communication facilitating monitoring, control and administration.
- Buffering of data in the event of loss of communication or power interruption. Common Optical Probe to connect to any Meter.
- Independent of field power supply (such as 110V, 220V, 440V).
- Common Data Acquisition and Management Software at Server end for any meter type and for any communication technology.
- Type tested for protection against Environment, EMI-EMC, Surge etc.
