Overview:

DDZY949, DDZY949-Z single-phase charge-control smart electric energy meters (hereinafter referred to as electric energy meters) adopt large-scale integrated circuits, apply digital sampling technology, and meet the requirements for electric energy meters in the "informatization, automation, and interaction" construction of smart grids. Designed and manufactured, mainly used for electric energy measurement of single-phase residential users in smart grids.


The main function:

With forward and reverse active power, combined active power total and sub-rate electric energy metering and storage functions, combined active power feature words can be set;

With the historical power storage function of the previous 12 settlement cycles, it can store the total and sub-rate power data of forward and reverse active power, combined active power;

There are two sets of rate time zone and timetable, which can be automatically converted at the agreed time;

With power failure display function, the display can be awakened by pressing the button after power failure;

With infrared communication port and RS485 communication port, it is convenient to exchange data with the outside world;

Using automatic software calibration technology, the calibration is simple, the consistency is good, and the accuracy is high;

Real-time measurement function: It can measure multiple grid operating parameters such as grid voltage, current, active power, power factor, and frequency.

It can record the last 10 power-downs, event resets, meter resets, time calibration events, total times of programming (including time period, time zone table, etc.), data information and operator code at the time of programming.

Record the total number of opening and closing of the meter cover, the time of the last 10 occurrences, the end time, and the power data after the meter cover is opened.

Power freezing function: with instantaneous freezing, timing freezing, hourly freezing, daily freezing, time zone table switching freezing, and day time table switching freezing.

Remote pull and close function: support remote power-on and power-off control, externally controlled electric energy meter is used in conjunction with the customer's circuit breaker.

DDZY949-Z single-phase fee-controlled intelligent electric energy meter with standard communication port, supports hot swap, supports the interchange of power line carrier communication modules of different manufacturers, and realizes the communication requirements of the AMI system for electric energy meters.

DDZY949-J single-phase fee-controlled intelligent electric energy meter with standard communication port, supports hot plugging, supports the interchange of RF communication modules of different manufacturers, and realizes the communication requirements of the AMI system for electric energy meters.
