DATA CONCENTRATOR UNIT(DCU) “МЕРИДІАН КДМ-01”
“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
Specifications
Notes:
- * – the backup channel is organized by connecting to the interface port of the Router modem or router (not included in the delivery kit) with an alternative mobile operator;
- ** – in case of deviations the possibility of time synchronization of the Router with the HES software with the subsequent synchronization of time of counters in the PLC network is provided;
- *** HES – Head End System (ASKOE system of Distribution System Operator or Commercial Accounting Service Provider).
