Electricity energy meter MODBUS RS-485 - three-phase LE-03M

Three-phase energy meter with MODBUS RS-485 communication

The LE-03M meter is an electronic, calibrated energy meter designed for measuring in three-phase networks. It serves to indicate and record consumed electrical energy, while simultaneously offering the possibility of remote data reading via the RS-485 communication port with the MODBUS RTU protocol. The device has a MID directive compliance certificate, which confirms its legality for billing applications.

Versatile application and reliability

The LE-03M meter finds application in both domestic and industrial installations. Thanks to the MODBUS RS-485 communication option, integration with energy monitoring and management systems is simple and effective. This is particularly useful for installers of intelligent building systems and for end-users who want to monitor their energy consumption in real time.

Key features and benefits:

• Three-phase measurement: Precise energy measurement in three-phase systems.
• MODBUS RTU communication: Remote data reading and configuration via the RS-485 port. Enables integration with building and industrial automation systems.
• MID certificate: Guarantee of measurement legality and possibility of use for billing purposes.
• S0 impulse output: Allows connection of external devices to register impulses generated by the meter, enabling additional energy consumption analysis.
• 7 module width: Compact dimensions facilitate mounting in electrical switchboards.
• Direct measurement: Measures energy directly, without the need for additional current transformers (in the standard version).
• Meter rollback lock: Protects against manipulation and ensures measurement reliability.

Technical specifications:

The LE-03M meter is characterized by the following parameters: maximum current 100 A, rated voltage 230/400 V, accuracy class B and frequency range 50 Hz. It has a protection degree of IP20, which ensures safe use in normal operating conditions. The impulse output is of the electrical type (S0), and the number of impulses is 800 imp/kWh (kvarh). The device is designed to measure active power.

Additional functions and possibilities:

The LE Config service program allows test reading of the accumulated energy value and basic setting of meter parameters using a PC computer. Programs such as MeternetPRO are also available, which allow remote reading of meter states and data transmission to an Excel system or a dedicated MT-CPU-1 server with a web application. The possibility of remote data reading significantly facilitates energy consumption management and cost optimization.

The LE-03M meter is a solid and reliable solution for anyone who needs precise measurement of electrical energy in a three-phase network with the possibility of remote data reading.
