Overview:

The three-phase three-wire smart energy meter adopts a high-performance metering chip, which can realize the advantages of small current measurement, high precision, and small temperature and frequency variation. It has the characteristics of stable performance, rich functions, and strong anti-interference ability. It is carefully designed in aspects such as fault, data security and abnormal power consumption analysis, and supports AC and DC adaptive auxiliary power supply. It adopts a fully sealed structure and shell, which can meet the harsh high and low temperature alternating hot and humid environment applications. The battery box and programming button can be sealed separately, which is convenient for the management of the power supply department.

Main features:

Wide viewing angle, large-screen LCD display, with rich status indication and Chinese character auxiliary prompt information

Dual RS-485, far infrared communication interface, independent of each other.

Time-sharing metering of forward active power, reverse active power and four-quadrant reactive power, supports any combination of combined active power and four-quadrant reactive power.

Time-of-use measurement of forward active power, reverse active power and four-quadrant reactive power maximum demand and occurrence time;

It can store up to 13 months of historical power and demand records, and the power data supports up to three settlements per month;

Maximum 8 tariffs, two sets of tariff schedules for master and backup, automatic error correction for dual backup of clocks;

Double backup data storage, automatic parameter error correction:

6 types of data recording load curves can be set, and the storage capacity can reach 2M bytes;

Comprehensive event record types, with anti-theft power-opening detection function;

Record and store voltage quality statistics for 13 months:

Rich self-test, error correction and alarm functions:

After a power failure, it can be woken up and displayed by a button or a manual reader, and far infrared meter reading;

10-level password protection, communication lock after multiple password errors, support single-level password locking function;

AC/DC self-adaptive auxiliary power supply, the auxiliary power supply will give priority to power supply after power-on:

Record a variety of frozen data to form a graphical abnormality analysis of electricity consumption composed of event records, load curves and frozen data.

Scope of use:

It is suitable for power plants, substations and various enterprises and institutions with high reliability and high stability electric energy metering requirements.
