Single-phase active and reactive energy meter, Modbus RTU, 100(5)A, MID LE-01MQ

Smart energy meter for domestic and industrial applications

This single-phase energy meter, with a maximum current of 100A, is designed for use in both domestic and more demanding industrial environments. It offers precise measurement of active and reactive energy, and thanks to the Modbus RTU interface, it allows easy integration with energy monitoring and management systems. It meets the requirements of the MID directive, which guarantees the accuracy and reliability of measurements.

Functionality and communication

The LE-01MQ meter is not only a measuring device, but also an element of an intelligent energy management system. Equipped with an RS-485 port and the Modbus RTU communication protocol, it enables remote data reading and device configuration. The S0 pulse output allows integration with external energy consumption recording systems. The backlit LCD display ensures readability of indications even in low light conditions.

• Bidirectional measurement: Records both energy consumption and delivery, which is particularly important in installations with renewable energy sources (e.g., photovoltaics).
• Modbus RTU interface: Enables easy integration with SCADA, BMS and other platforms for monitoring energy consumption.
• S0 pulse output: Allows connecting the meter to external devices recording energy consumption (e.g., alarm systems, controllers).
• MID compliant: Guarantees the legality of measurements and the possibility of using the meter in settlements with the energy supplier.
• Wide voltage range: Adapted to work in networks with a voltage of 230V AC.
• Accuracy class B: Ensures precise energy consumption measurements.

Installation and technical parameters

The LE-01MQ meter is mounted on a standard 35mm rail and occupies 7 modules in width. It has a protection class of IP20, which means protection against touching with fingers and against the ingress of solid objects larger than 12.5 mm. Device configuration is done using the menu available on the LCD display and via the RS-485 communication port using dedicated LE Config or MeternetPRO software.

The maximum current (Imax) is 100A, the rated voltage (Un) is 230V AC, and the rated current (In) is 5A. It has an RS-485 communication interface and supports the Modbus RTU communication protocol. The pulse output is of the S0 type, and the accuracy class is B. The width of the meter is 7 modules, and the protection class is IP20.

This meter is a solid solution for anyone who needs precise measurement of electricity consumption and the possibility of remote monitoring and control. It is ideal for both installers looking for a reliable device to install for customers, and for end users who want to better understand their energy consumption and optimize costs.
