Electricity meter - three-phase RS-485, reactive energy LE-03MQ

Three-phase electricity meter with RS-485 interface

The LE-03MQ meter is an advanced device designed to measure electricity consumption in three-phase installations. Thanks to MID certification, it ensures measurement accuracy and reliability, which is crucial for both billing with the energy supplier and monitoring consumption in commercial and industrial buildings. The device is versatile – it can operate in both single-phase and three-phase systems.

Versatile application and remote reading

The LE-03MQ meter allows you to measure active and reactive energy, as well as record parameters of the power supply network. Equipped with an RS-485 communication interface with Modbus RTU protocol, it enables remote data reading and integration with energy consumption monitoring systems (e.g., SCADA). This facilitates data analysis, consumption optimization and quick detection of any irregularities. Additionally, it has an S0 pulse output, which allows integration with other measurement systems.

Solid construction and compliance with standards

The meter has been designed with durability and reliability in mind. Mounting is done on a standard DIN rail, which simplifies installation. It has a counter rollback lock and password-protected configuration, which protects against unauthorized changes to settings. Accuracy class B guarantees precise measurements, and IP20 protection degree provides protection against touch and dust. It meets the requirements of the MID (Measuring Instruments Directive), which confirms its compliance with European metrological standards.
