This MID-certified device ensures high accuracy and reliability for residential and commercial sub-metering applications, supporting both import and export energy measurement.

## Long description

The VCX SDM120M is a high-precision single-phase bidirectional energy meter engineered for accurate monitoring of electricity consumption and production. This device is designed to measure both imported and exported energy, making it an ideal solution for modern electrical installations that require detailed data tracking. Equipped with a built-in Modbus communication interface, the meter allows for efficient integration into smart energy management systems, building automation, and remote monitoring platforms.
Advantages
The primary benefit of the VCX SDM120M is its MID certification, which guarantees high measurement accuracy and compliance with strict European standards for billing and sub-metering applications. Its bidirectional functionality is particularly advantageous for users with renewable energy sources, such as photovoltaic systems, as it tracks both energy drawn from the grid and energy fed back into it. The compact design ensures easy installation in standard distribution boards, while the digital interface provides reliable data transmission for real-time analysis.
Suitable for
Residential energy monitoring and sub-metering
Commercial facility electricity management
Photovoltaic system energy production tracking
Smart home and building automation integration
Industrial energy consumption analysis
When it may not be suitable
This device is designed exclusively for single-phase electrical systems and cannot be used in three-phase installations. Additionally, it is intended for sub-metering purposes and may not be suitable as a primary utility billing meter depending on local grid operator regulations.
Key specifications
Measurement type: Single-phase bidirectional
Communication: Modbus RTU interface
Certification: MID approved
Mounting: DIN rail mountable
Display: Digital LCD
How to use
The meter should be installed by a qualified electrician in accordance with local electrical codes. It is mounted on a standard 35mm DIN rail within a distribution board. Once physically installed and wired to the power circuit, the Modbus interface must be configured via the device settings to communicate with your central management system or data logger. The digital display allows for local verification of energy values, while the communication port handles remote data polling.
What to consider before purchase
Ensure your electrical system is single-phase
Verify compatibility with your existing Modbus-enabled monitoring system
Check available space on your DIN rail
Confirm if MID certification meets your specific legal or billing requirements
Usage recommendations
For optimal performance and data accuracy, ensure that the communication wiring is shielded and properly grounded to prevent signal interference in industrial or high-noise environments.
