Carlo Gavazzi Automation, the international electronics group active in the design, manufacture, and marketing of electronic equipment, is proud to announce the launch of the EM630 W and EM640 W, the new Wi-Fi-enabled versions of the EM600 Series of three-phase energy analyzers.
Based on the proven EM600 B (Ethernet) range, the EM600 W adds secure wireless connectivity for fast and flexible integration into energy management systems. It supports both Wi-Fi 1-to-1 (Access Point) mode for direct configuration via the embedded webserver and Wi-Fi LAN operation for seamless existing network integration, providing a simple and reliable alternative or complement to Ethernet communication.
“With the launch of the EM600 W, we extend our connected energy-metering platform by combining flexibility, ease of integration, and cybersecurity,” says Andrea Bernardi, International Product Manager. “The addition of Wi-Fi and multiprotocol capability makes it ideal for industrial, building, renewable, and submetering applications.”
The EM600 W is a highly versatile multiprotocol platform, enabling Ethernet and/or Wi-Fi communication alongside Modbus RTU or M-Bus via plug-in modules (O1, S1, M1). This ensures maximum flexibility for both new installations and retrofit projects. MID-certified for fiscal and sub-billing applications, this analyzer guarantees accuracy and compliance with national regulations. It supports Modbus TCP/IP, HTTPS REST API, and features an integrated webserver for configuration and data monitoring.
An onboard datalogger, real-time clock, and NTP synchronization enable detailed energy analysis with hourly, daily, and monthly comparisons. Designed with advanced cybersecurity standards, the EM600 W ensures secure data communication and is RED DA certified and CRA-ready for long-term system integrity.
