Single-phase electric energy meter DDZY150

panel-mountRS-485smart

Single Phase Smart Energy Meter with GPRS The DDZY150 is a cost-effective solution for smart metering, data reading and load balance operations. The meter goes with direct connection type, The meter is manufactured by ISO9001 standards and IP54 protection rating. It offers two way communication via modular Ethernet/GPRS/PLC/RF com port and allows dynamic AMI interactions and reliable metrological operations at the same time. Main Features: 1. Automatic data logging usage and load profiles 2. Detection of significant reverse energy (SRE) 3. IEC62056-21 compliant optical & RS485 port allowing for easy data interrogation 4. On-demand and automatic load limiting profile settings 5. Built-in contactor and relay to remotely disconnect load and sub-meters (on request) 6. Tamper detection and event record such as cover open, black-out, magnetic field 7. Maximum demand measurement 8. Detailed power information such as phase voltage, current, total active power, reactive power, apparent power, total power factor, power grid frequency 9. PLC/ RF/ GPRS/GSM communication with a head-end AMR/AMI server 10. Time of Use (TOU) / 4 tariffs /8 time divisions /100 holidays 11.
