DTZY566-J three phase smart electricity meter adopts LSI technology & SMT technique to realize rated frequency 50Hz/60Hz import and export active energy measuring, four quadrant reactive energy measuring with high-reliability, wide dynamic working range, high accuracy, lower power loss features and TOU or step tariff, MD measuring, load curve functions. It can be used for AMR (automatic meter reading) system with wireless mesh network module (WMN).
DTZY566-J three phase smart electricity meter conforms to the standards as follow: IEC 62053-21, IEC 62053-22, IEC 62053-23, IEC 62052-11, and the ISO 9001 quality management system.

1. Total active energy and four tariffs active energy for import and export, active energy of each phase for import and export, reactive energy of four quadrants;
2. Active MD and occurrence time for import and export, active MD and occurrence time of four tariffs for import and export;
3. Display voltage and current of each phase, active power, reactive power, apparent power, power factor of total and each phase, frequency;
4. Last 12 billing data of total energy and four tariffs energy for import and export;
5. Energy frozen function: Given time frozen, real-time frozen, condition frozen, daily frozen and hourly frozen;
6. Load curve record with six channels;

7. Event log, the 10 latest event records of programming, MD reset, time correcting, phase failure, unbalance of current, negative phase sequence, meter cover opening, terminal cover opening, over load, power blackout, voltage-loss, current -loss and all voltage-loss, permanently keeps the occurrence time and accumulative energy for energy clear event.
8. Blackout waking up by key pressing or infrared communication, blackout meter data viewing key pressing;
9. Wireless mesh network communication 433MHz or 470MHz, communication module can be changed online, independent infrared and RS485 communication interface;
10. Step tariff function (optional);
11. Realizing remote prepayment function by installing ESAM (Embedded secure access module).
