Data concentrator units used to interrogate meters, to process and store the information it receives, and to send this data to a centralised Information System.
Installed on the LV side of the MV/LV distribution substations, the hub is a powerful computerised unit, which primarily:


• Centralises and processes meter data from a cluster of electric meters communicating via PLC (Power Line Communication)
• Sends data collected to an IS (Information System) via GPRS
• Sends remote handling requests from the IS to meters
• Tracks LV distribution network voltages
• Provides the interface with other devices (e.g. Fault Detectors)
• Main characteristics

• imensions 184 x 175 x 80 mm
• Fastened using 3 screws or clipped to DIN rail
• Protection ratings IP 51 / IK 07
• 200 – 250 V AC three-phase supply
• 2 Ethernet ports
• USB extension
• 4 dry contacts
• Optional GSM / GPRS modem
• CPL G1 or G3 protocol
• Advantages
• Concentration and management of meter data
• Compatible with all communication meters in PLC G1 or G3 (depending on hub version)
• Communication gateway between the IS and the meters
• Sending of secure data with certification and cryptographic mechanisms
• Reduced meter reading costs
• Compliance with European regulations in terms of electricity billing
• 20-year service life
• Uses
• Distribution Grid Managers responsible for metering (France and International)
• AMM (Advanced Meter Management) contracts from electricity suppliers
