Bi directional metering single-phase electricity meter double rate

Rail mounted energy meters are the core equipment used for energy measurement and monitoring in modern distribution systems, adopting standardThe DIN35 guide rail installation structure is different from traditional panel mounted energy meters, and has significant advantages such as compact size, simple wiring, flexible installation, and easy maintenance. It is widely used in commercial buildings, residential communities, factories and workshops, schools and hospitals, data centers, and various terminal distribution circuits, and is an important basic equipment for achieving refined electricity management.

From the perspective of structural design, this series of rail type electric energy meters strictly follow industrial design specifications. The body adopts a high-strength flame-retardant engineering plastic shell, which has excellent insulation performance and impact resistance, and can effectively prevent leakage, short circuit, and external damage. The overall size is small, lightweight, and does not take up too much space in the distribution box, making it particularly suitable for dense installation inside terminal distribution boxes, metering boxes, and distribution cabinets. The wiring method of the product is simple and clear, using plug-in or screw fastening terminals. The wiring is firm and reliable, with anti misoperation and anti loosening design, which can improve installation efficiency and reduce the difficulty of later operation and maintenance. At the same time, the watch body is equipped with a high-definition LCD display screen, which can intuitively display multiple electrical parameters such as cumulative energy, real-time voltage, current, power, power factor, frequency, etc. The data is refreshed quickly, the display is clear and easy to understand, and it meets the needs of quick on-site viewing and meter reading.

In terms of measurement performance, the rail type electric energy meter adopts high-precision measurement chips and mature electric energy measurement algorithms, and the measurement accuracy can reachNational standards such as 0.5S and 1.0 can accurately measure active energy, and some models can also achieve extended measurement of reactive energy, demand, harmonics, etc., meeting high-precision measurement needs in different scenarios. The product has good linearity and stability, and can maintain accurate measurement under complex working conditions such as light load, heavy load, and fluctuating load, effectively avoiding electricity disputes caused by measurement deviations. At the same time, the equipment has a wide voltage and frequency working range, which can adapt to industrial environments with large fluctuations in the power grid and unstable power supply scenarios. It has strong anti-interference ability and can resist the effects of electromagnetic interference, surge impact, harmonic pollution, etc. It can operate stably and reliably for a long time, with low failure rate and long service life.

Communication and intelligent functions are the core highlights of modern rail mounted energy meters. Mainstream products are standardRS485 communication interface, supporting standard communication protocols such as Modbus RTU and DL/T645, can easily connect to energy management systems, intelligent distribution systems, building automation systems, and remote meter reading platforms, achieving real-time data upload, remote meter reading, remote monitoring, abnormal alarm and other functions. Some models support extended functions such as Ethernet, LoRa, 4G wireless communication, etc., meeting the needs of wireless networking and long-distance transmission. Through the supporting management software, users can achieve intelligent operations such as electricity data statistics, energy consumption analysis, load monitoring, peak and valley metering, overdue tripping, and prepaid management, greatly improving the efficiency of electricity management, reducing manual meter reading costs, and helping users achieve energy conservation, consumption reduction, and intelligent operation and maintenance.

Safety and reliability design are integrated throughout the entire product process. The rail type electric energy meter has overvoltage, overcurrent, overload, voltage loss, and phase interruption protection functions, which can monitor the abnormal status of the circuit in real time. Some models support fault alarm and event recording functions, which can automatically record event information such as overcurrent, voltage loss, and cover opening, making it easy to troubleshoot and trace responsibility. The product is produced and manufactured strictly in accordance with relevant national standardsCMC measuring instrument license, 3C certification and other testing comply with the technical specifications of the power industry, ensuring legal and effective measurement, safe and stable operation.

Overall, rail mounted energy meters have become the mainstream metering equipment for low-voltage distribution terminals due to their compact structure, high-precision measurement, stable and reliable performance, and intelligent communication capabilities. They are not only suitable for traditional power metering scenarios, but also meet modern management needs such as smart grids, smart buildings, and energy consumption dual control, providing users with safe, accurate, and efficient electricity metering and management solutions.
