Suitable for
Industrial facility energy monitoring
Commercial building energy management systems
Residential smart home energy tracking
Remote electrical consumption data acquisition
When it may not be suitable
This meter is not intended for single-phase electrical installations, as it is specifically calibrated for three-phase systems. Furthermore, it is not suitable for environments where the electrical parameters exceed the technical specifications of the device or where a non-digital, mechanical display is preferred.
Key specifications
Three-phase measurement capability
Integrated MODBUS RS-485 communication interface
Measurement of active electrical energy
Designed for standard distribution board mounting
How to use
The device should be installed by a qualified electrician in accordance with local electrical safety regulations. It is mounted on a standard DIN rail within an electrical distribution cabinet. Once physically installed, the MODBUS RS-485 interface must be connected to the communication bus of the building management system. Configuration of the communication parameters, such as the device address and baud rate, should be performed via the interface to ensure proper data exchange with the master controller.
What to consider before purchase
Ensure the electrical installation is three-phase
Verify compatibility with your existing MODBUS RS-485 master controller
Confirm available space on the DIN rail within your distribution board
Check that the voltage and current ratings match your specific application requirements
Usage recommendations
For optimal performance and data integrity, ensure that the RS-485 communication lines are properly shielded and terminated according to standard industrial practices to prevent signal interference.
