Single-phase active and reactive energy meter, Modbus RTU, multi-tariff LE-01MW

Smart energy consumption measurement with LE-01MW meter

The LE-01MW meter is an advanced device designed for precise measurement of electricity consumption in single-phase installations. Thanks to its compliance with the MID directive, it ensures reliability and accuracy of measurements, which is crucial for both professional installers and end-users. The device is particularly useful in tariff systems, enabling optimization of energy costs.

Versatile application and functionality

The LE-01MW meter is designed to operate in a direct 2-wire system, simplifying installation and configuration. Equipped with an RS-485 communication interface with Modbus RTU protocol, it enables remote data reading and device configuration. This greatly facilitates integration with energy consumption monitoring systems and remote installation management. The built-in real-time clock allows for measuring energy consumption with a breakdown into 4 tariff zones, which is particularly important for customers using dynamic energy prices.

Solid construction and safety

The LE-01MW meter is characterized by high quality workmanship and durability. DIN rail mounting (1 module) ensures easy installation in standard electrical panels. Accuracy class B guarantees precise measurements, and the IP51 protection degree protects the device from dust and moisture. The use of a counter tamper lock minimizes the risk of unauthorized manipulation. Overload capacity of 30×Imax/10ms ensures resistance to short-term overvoltages.

• Multi-tariff measurement allows for billing energy consumption in different time zones, optimizing costs.
• Modbus RTU communication provides easy integration with monitoring and remote data reading systems.
• MID compliance guarantees legalization and measurement reliability.
• Compact dimensions – DIN rail mounting (1 module) saves space in the distribution board.
• Wide voltage range – measures voltage in the range of 100÷289 V AC, ensuring compatibility with various installations.
• Safety – counter tamper lock protects against manipulation and high insulation protection class II protects against electric shock.
• Accuracy – accuracy class B ensures precise measurement of electricity consumption.

Additionally, access to the free LE Config service program facilitates configuration and data reading from the meter, and compatibility with the MeternetPRO application enables remote monitoring of electrical network parameters.
