FEATURES

The meter box has a small volume, with regular and neat internal wiring that meets the requirements of power distribution. It is easy to install, maintain, and upgrade;

◎ LCD display with backlight. Display information: household number, cumulative, remaining, overdraft, time, voltage, current, power, electricity price, fault, power outage, communication, etc.

The incoming end of the electric meter adopts dedicated wiring terminals (special molds) with strong current carrying capacity, which is convenient for on-site construction;

The electric meter adopts imported multifunctional, multi resource, higher integration, and faster running processor control chips (industrial grade) with modular structure design and strong anti-interference ability;

The electric meter adopts a dedicated three-phase energy metering chip, which has a short measurement cycle, high accuracy, stable performance, and long service life, effectively preventing electricity theft;

The communication circuit of the electric meter adopts lightning protection circuit, and the signal adopts photoelectric isolation. The communication circuit is separated from other circuits of the electric meter for processing, which can greatly reduce the damage of lightning strikes to the electric meter;

The metering circuit and communication display circuit adopt dualCPUStructure, one supervisor for measurement, one supervisor for communication indication and display, communication does not affect measurement;

Single and three-phase can be set arbitrarily through software.

The interface of the electric energy signal acquisition module adopts a computer specific interface, which has undergone special processing to ensure reliable signal transmission;

The internal strong and weak electricity are isolated by galvanized shielding plates, which can reduce the interference of strong electricity on weak electricity signals;

There is a relay inspection device inside, which has a phase loss protection function.

◎ Data * *: Various data parameters of the electricity meter are encrypted using algorithms to ensure data * *;

◎ It has real-time power query function, which can query the user's electricity load in real time;

◎ Transformer type electric energy meter, using external transformers to measure high currents, with measurement accuracy up to0.5SGrade; Can provide users with a set of control points;

◎ Direct access type electricity meter, * * The number of large single-phase users is36Users can flexibly set the number of three-phase users; Transformer type electric energy meter, * * The number of large three-phase users is8Users can flexibly set the number of three-phase users;

Internal three-phase power supply, with power phase loss indication function; The power supply is out of phase, and the electricity meter is working as usual;

◎ Network communication function, provided by the electricity meterRS485Interface, can be directly assembledRS485Communication network or networking of other communication methods through converters.

Functional Features

◎ Prepaid (Countdown) function: Users must purchase electricity before using it, and there are various payment methods available for power outages due to overdue payments.

Multi functional: It has dual functions of multi rate and tiered electricity pricing. Ladder: 8 staircases, 8 electricity prices, two sets of staircases, supporting ladder switching; Multiple rates: 8 time zones, 8 time slot tables, and 8 time slots per time slot table;

Ladder function: can divide monthly electricity consumption into8 tiers, with different unit prices (tiered electricity prices) set for each tier. The unit price of the tier where the user's electricity consumption reaches will be executed, that is, if the electricity consumption is low, the electricity price will be low, advocating residents to save electricity;

Multi rate function: Divide a year into8 time zones, each time zone can set 8 time periods, corresponding to 8 rate unit prices, to achieve different billing rates for different time periods in different time zones, encouraging users to use electricity during low peak periods and playing a guiding role in electricity consumption;

Monthly settlement function: You can set a monthly settlement date, execute monthly settlement based on the set monthly settlement date for multiple rates and tiered electricity prices, save the electricity consumption for the current month, and the corresponding electricity consumption for each rate;

◎ Control function: There are relays inside that can control and monitor user electricity usage.

◎ Detection function: There is a relay detection module inside, which can detect the user's electrical status and prevent damage to the user's equipment caused by phase loss.

◎ Overload protection (current limiting) function: When the user's load exceeds the allowable maximum load, the user automatically loses power protection.

◎ Power off automatic recovery function: After the user loses power protection, within the specified number of power outages, if the user's power consumption drops to the allowable range, the system can automatically restore power supply.

◎ Low battery alarm function: The alarm battery level can be set. When the user's electricity consumption is lower than the set value, the battery level display window of the meter will automatically flash or give a power-off prompt to the user.

◎ Allow overdraft power function: Different overdraft power can be set according to the user's reputation. If the set parameters are exceeded, the power will be cut off due to overdue payments.

◎ Total metering function: It can measure and count the cumulative electricity of multiple user outgoing lines and circuits (direct access type).

◎ Phase loss protection function: In the event of a phase loss for three-phase users, the relay automatically disconnects to provide protection.
