1CE certified high-precision intelligent energy meter

The CE certification of an electric meter is an important safety certification that signifies that the meter product has fully met the requirements of various directives on safety, health, and environmental protection within the European Economic Area (EEA). CE， The full name "Conformit é Europ é enne" means "compliant with European standards", which proves that the product has successfully passed all necessary tests and evaluations, complied with EU laws and regulations, and is able to freely circulate in the European market.

For electric meters, CE certification covers multiple key areas such as electrical safety, electromagnetic compatibility (EMC), and energy efficiency. Among them, electrical safety is the core element of CE certification, ensuring that the electricity meter has multiple protection functions such as anti electric shock, overload, and short circuit; EMC focuses on the electromagnetic interference that electricity meters may generate during operation and their ability to resist external interference; In terms of energy efficiency, it is required that the electricity meter demonstrate efficient and accurate performance in measuring electrical energy.

Electric meter products that have obtained CE certification not only qualify for legal sales in the European market, but also significantly enhance their market competitiveness and brand image. At the same time, this is also a solid guarantee for consumer safety rights, as CE certification means that the product has strictly met the high standard requirements of the European market.

2、 Features of Electric Meter Functions-CE certified high-precision intelligent energy meter

In terms of high-precision measurement, the ADL400N-CT/D24 electric meter adoptsThe measurement technology can accurately sample and comprehensively monitor all electrical parameters in real-time, covering key indicators such as voltage, current, active power, reactive power, apparent power, power factor, and frequency. The voltage measurement accuracy is as high as one decimal place, and the current measurement accuracy is accurate to two decimal places. The measurement errors of active power, reactive power, and apparent power are strictly controlled within ± 0.5%, ensuring the accuracy and reliability of the measurement data;

In terms of bidirectional metering function: This meter supports precise bidirectional metering of the power generation of photovoltaic systems and the electricity consumption of users, achieving intelligent management of energy flow in both directions. For household distributed photovoltaic systems, this function is particularly important as it helps users to clearly grasp the power generation benefits of the photovoltaic system, while finely managing the electricity consumption of households or enterprises, and easily achieving intelligent scheduling strategies of "self use and surplus electricity grid connection";

In terms of anti backflow function: The electricity meter can seamlessly communicate with the inverter or energy management system (EMS), and intelligently execute anti backflow strategies based on real-time power and accumulated energy. Once a reverse flow trend is detected, the meter will immediately notify the inverter to adjust the output power until the reverse output current returns to zero, ensuring the safe and stable operation of the power grid and effectively avoiding any impact on the power grid;

Quick response is another highlight of this electric meter: the response rate of voltage, current, and power does not exceed 100ms, and the response rate of electrical energy only takes 1 second. It can quickly capture subtle changes in power parameters and provide timely feedback on the operating status of the system, providing a solid guarantee for real-time monitoring and precise control;

In terms of installation convenience: The electric meter adopts the standard DIN35mm rail installation method, which is small and exquisite in size, does not occupy too much space, and the installation process is simple and fast. This design is particularly suitable for scenarios such as household photovoltaics and industrial and commercial energy storage, greatly improving installation efficiency.

In terms of monitoring and measurement functions: In addition to basic power parameter measurement capabilities, electric meters also support rich functions such as phase separated energy measurement and harmonic monitoring. It provides comprehensive detection of 2-31st harmonic voltage, current, and total harmonic content, which helps to analyze power quality in depth and provides strong data support for system optimization and precise control;

In terms of communication interface, the electricity meter is equipped with RS485 communication interface, supporting Modbus RTU communication protocol, which facilitates efficient data communication and networking with other devices. This enables ADL400N-CT/D24 meters to easily connect to various energy management systems and SCADA systems, achieving remote monitoring and intelligent data management;

In terms of application scenarios, this meter is widely used in new energy generation systems such as photovoltaic grid connected systems, micro inverter systems, energy storage systems, and AC coupling systems. Whether it is home photovoltaic systems, industrial and commercial energy storage systems, or scenarios such as microgrids and charging piles, they can fully leverage their advantages in measurement and management.
