Three Phase RS485 Modbus DIN Rail Digital Energy Meter has become the choice of modern industry and energy management with its excellent communication performance, high-precision measurement capability, and convenient installation and maintenance features. Whether it is substation automation, distribution automation or intelligent buildings, this energy meter can provide reliable and efficient data support to help users achieve efficient management and optimization of energy.

Excellent performance of RS485 communication interface
The RS485 communication interface used by Three Phase RS485 Modbus DIN Rail Digital Energy Meter is a leader in the field of industrial communication. This interface transmits through differential signals, that is, it detects the voltage difference between two lines (line A and line B) instead of the absolute voltage value. This feature makes it effectively resistant to common mode noise interference, especially suitable for communication over long distances and harsh environments. RS485 supports multi-point, half-duplex communication, allowing multiple devices to be mounted on the same bus, each device has a unique address, and realizes efficient network configuration.

Wide application of Modbus protocol
The energy meter also adopts the widely used Modbus communication protocol, which is an open and standardized serial communication protocol widely used in industrial automation. The Modbus protocol is based on a master-slave architecture. The master device can send requests to the slave device (such as this product), and the slave device returns the corresponding data according to the request. This protocol is simple and easy to implement, and supports multiple data transmission modes, including RTU (remote terminal unit) and ASCII mode, providing users with flexible data interaction methods.

High-precision measurement and versatility
The Three Phase RS485 Modbus DIN Rail Digital Energy Meter not only has powerful communication capabilities, but also excels in measurement accuracy and functionality. It can accurately measure parameters such as three-phase current, three-phase phase voltage, three-phase line voltage, three-phase active power, three-phase reactive power, three-phase apparent power, three-phase total power factor, frequency, and three-phase active energy and three-phase reactive energy. The comprehensive measurement of these parameters provides comprehensive and accurate data support for power monitoring, energy metering, and energy consumption analysis.

Convenient installation and maintenance
The electric energy meter adopts DIN rail installation, which not only simplifies the installation process, but also improves the stability and reliability of the equipment. At the same time, the electric energy meter has the function of field programmable input parameters. Users can adjust the measurement parameters such as range, zero point, etc. according to actual needs to meet the needs of different application scenarios. In addition, the combination of LED field display and remote RS-485 digital interface communication makes data reading and transmission more convenient.
