Main Features (Features)

The meter structure adopts modular design, with strong anti-interference ability and stable performance;

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

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,

The electricity meter is manufactured using internationally advanced specialized ultra large scale integrated circuits and SMT technology, with a high degree of integration;

Each household's electricity meter measures independently, with high accuracy, centralized display, and no interference between households;

※ It can simultaneously measure and detect up to 13 households (three-phase);

The meter box has a small volume and is easy to install, maintain, and upgrade;

Accurate measurement, long service life, effective prevention of electricity theft, and easy management;

※ It has a power phase loss indication function;

The internal power supply is three-phase, but there is a phase loss in the power supply. The electricity meter works as usual;

Data Security: Various data parameters of the electricity meter are encrypted using encryption algorithms to ensure data security;

The incoming and outgoing lines of the electric meter use dedicated wiring terminals, which are convenient for on-site construction;

The communication circuit design of the electricity meter adopts lightning protection circuit and photoelectric isolation. The communication circuit is separated from the electricity meter circuit to reduce the damage of lightning strikes to the electricity meter.

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 measurement circuit and communication/display circuit adopt a dual CPU mechanism, which does not affect the measurement during communication.

※ Effectively prevent and control electricity theft.
