“КДМ-01`` DCU is designed for:

  • data collection from single-phase meters via power wires, PLC technology

  • data collection from three-phase meters via power wires, PLC technology

  • data acquisition(information storage period – not less than 45 days)

  • logging system events

  • transmission of the collected information to the upper level (to the software of HES-systems) via GSM / GPRS communication channel
