DETAILED DESCRIPTION

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.

By adding Wi-Fi and multi-protocol capabilities to the EM600 W analyzer series, connected energy measurement platforms are expanded by combining flexibility, ease of integration and cybersecurity, making it ideal for renewable energy, industrial and building applications, as well as sub-metering 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.

All features are housed in a compact, self-powered 4-DIN module, delivering the same high performance as the EM600 B, including fast refresh rates and SUNSPEC compliance.

EM630 is an energy analyser connected through 5 A current transformers or 333 mV current sensors, for three phase, two phase and single phase systems up to 480VL-L.

Modbus TCP/IP and HTTPS rest API communication are available via Ethernet port and/or WI-Fi. According to the model, a digital input combined with digital output, a Modbus RTU or an M-Bus port are available thanks to additional patented sliding module. W versions also feature Wi-Fi connection and RTC synchronization.

Applications

EM630canbeinstalled in any low-voltage switchboard, to monitor the energy consumption, the main electrical variables and the harmonic distortion. Compatible with any current transformer with 5 A secondary current, it

can be installed in systems with rated current up to 10 kA, even in retrofit applications if used with openable transformers like CTA, CTD S or CTVs.

If used to monitor a single machine, it provides all the main electrical variables to identify any possible malfunction in its early stage and can correlate the energy consumption with the hours of operation, to plan

maintenance and prevent failures. The partial meter reset function, easily implementable by means of a digital input, allows you to monitor each individual machine cycle.

Thanks to the measurement refresh time (100 ms) and to the high resolution of the variables available through Modbus communication modules, it can also be used as data source for control actions, such as avoiding feeding energy into the electricity grid in a photovoltaic installation with energy storage

EM640 is a direct connection energy analyser, for single- and three-phase systems up to 480 V L-L and current up to 65 A.

Modbus TCP/IP and HTTPS rest API communication is available via Ethernet port and/or Wi-Fi. According to the model, a digital input combined with digital output, a Modbus RTU or an M-Bus port are available thanks to additional patented sliding module.W versions also feature Wi-Fi connection and RTC synchronization
