Product detailed description:

◆Active energy metering, long-term work error progress does not require calibration;

◆The case adopts a sealed dust-proof structure, which is flame retardant, anti-aging, and has a long service life of up to10Year;

◆Simultaneous sampling of phase current and neutral current, using the larger one for effective sampling, to completely prevent electricity theft from one fire and one ground;

◆There are few peripheral components, low power consumption, simple meter structure, and all components in the meter are made of long-life and highly reliable electronic components, thus possessing the characteristics of long life and high reliability performance;

◆Adopting the latest imported power specific digital integrated circuit with built-in digital multiplier. Greatly improved the dynamic working range of the electricity meter;

◆Equipped with infrared communication andRS485Communication function, which can be accessed through the electricity meterRS485Interface reading of total power consumption and settings Electricity meter communication address and setting the minimum reading; Infrared communication andRS485Communication is designed independently at the physical layer, andRS485Unified communication interface and infrared communication interface functions;

◆Information adoptionLCDDisplay method.LCDContrast ratio:>4, viewing angle width:>40°,Working temperature range:-30～70℃Working life:≥15It has functions such as UV protection, moisture resistance, etc;
◆The hardware of the electric meter adopts an imported varistor+thermistor+power frequency transformer structure, which has good surge absorption and overvoltage protection, as well as lightning protection function; In terms of software, multiple data backups and real-time verification are used to ensure data security and improve the system's anti-interference ability. Data can be saved for a long time (can be saved during continuous power outages)10Over years old);
