Single Phase GPRS Smart Electricity Meter

The meter works with a plug in module for DLMS/COSEM compliant data collection and network communications. This modular design enables utility to select from PLC/RF/GPRS/3G and 4G LTE cellular data networks according to local conditions at low cost. Upgrade and maintenance will also become cost-effective by replacing the modules only instead of the entire meter.

Main Features

  •            1, DLMS/COSEM standard compliant
  •            2, Detection of significant reverse energy (SRE)
  •            3, IEC62056-21 compliant optical & RS485 port allowing for easy data interrogation
  •            4, Disconnects on overload and no credit
  •            5, Prepayment and credit mode hot swap
  •            6, Programmable load limit and low credit warning
  •            7, Detection and record tamper event such as opening cover, reverse connection, black-out
