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

Post payment (positive counting) function: Traditional mode, first use electricity and then pay.

◎ Remote transmission function.

◎ 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.

◎ Card insertion function: Add card insertion communication methods according to user needs (specially customized).

◎ 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.
