Two-way 3-phase energy meter LE-03ETH-CT Ethernet, Modbus TCP

Smart three-phase energy meter with Ethernet communication

The LE-03ETH-CT meter is an advanced device designed for precise measurement of electricity consumption in three-phase installations. Thanks to the built-in Ethernet interface and Modbus TCP protocol support, it enables remote data reading and integration with monitoring and energy management systems. It is an ideal solution for both professional installers and end-users looking for an effective way to control energy costs.

Precision and versatility of measurements

The LE-03ETH-CT meter provides accurate measurement of active and reactive energy in both directions, as well as a number of network parameters, such as voltage, current, frequency, active and reactive power, and power factor. It meets the requirements of the MID 2014/32/EU directive (has a MID declaration), which guarantees its legalization for settlements with the energy supplier. The ability to work in semi-indirect (with current transformers) or indirect (with voltage and current transformers) systems increases its flexibility and adaptation to different installation configurations. The accuracy of active energy measurement is class B (EN504070-3:2022), and reactive energy class 2 (IEC62053-23).

Communication and installation

The built-in Ethernet port and Modbus TCP protocol enable easy integration of the meter with existing building or industrial automation systems. A clear, backlit LCD display shows the current values of measured parameters. Mounting on a standard 35 mm rail is simple and quick, and the compact dimensions (4 modules – 70 mm) allow for installation in limited space. Screw terminals with a cross-section of 2.5 mm² ensure safe and durable wire connections. The meter operates in a wide temperature range from -40°C to 70°C and has a protection degree of IP51.
