Three-phase bidirectional indirect, semi-indirect meter, Modbus RTU, 100(5)A. MID LE-03MQ-CT

Three-phase energy meter – precise measurement and remote reading

This advanced three-phase energy meter, designed for systems with a neutral wire, combines functionality, accuracy and the ability to integrate with modern energy management systems. Ideal for both professional installers and end-users, it provides reliable measurements and control of energy consumption. The device is certified according to the MID directive, which guarantees its legalization and compliance with applicable standards.

Functionality and application

The LE-03MQ-CT meter is a versatile device that measures both active and reactive energy consumption and return. This makes it suitable for applications related to prosumer energy, where the user can both draw energy from the grid and return it to it (e.g. from a photovoltaic installation). Equipped with a Modbus RTU interface and an RS-485 port, it enables easy integration with monitoring systems and remote data reading. The S0 pulse output allows connection of additional devices recording energy consumption.

• Bidirectional measurement: Records both energy consumption and return.

• Modbus RTU communication: Enables remote data reading and integration with building automation systems (BMS) or energy management systems (EMS).

• MID compliant: Guarantee of legalization and measurement accuracy.

• Wide voltage range: Supports rated voltages from 230 to 400 V.

• S0 pulse output: Allows connection of external devices recording energy consumption.

• DIN rail mounting: Facilitates installation in electrical panels.

Construction and technical parameters

The LE-03MQ-CT meter is characterized by a solid construction and high quality workmanship. The housing with IP20 protection provides protection against touch and dust. The device occupies 4.5 modules on a DIN rail, which allows for easy mounting in standard electrical panels. Accuracy class B ensures precise energy consumption measurements. The meter's anti-tamper lock protects against manipulation and unauthorized access to data.
