Shelly Pro 3EM 120A v2 is a professional DIN-rail mountable three-phase energy meter designed for high-precision monitoring. This next-generation device features 4-quadrant measurement and supports both single-phase and three-phase electrical systems. With integrated Wi-Fi, LAN, and Bluetooth connectivity, it enables real-time monitoring of voltage, current, active power, and apparent power for each phase individually.
The meter is Matter-ready and complies with Class B active energy accuracy (IEC 62053-21). It features non-volatile memory capable of storing at least 45 days of historical data at 1-minute intervals, ensuring data retrieval even during network interruptions. Its advanced firmware supports MODBUS for industrial applications and custom scripting for complex automation scenarios, such as managing PV systems or EV charging based on energy production.
Safety and precision features include phase sequence error detection, internal temperature sensing, and an optical pulse indication of energy usage. While the device does not have a built-in relay, it can be expanded with a Shelly Pro Addon to control external contactors based on measured parameters.
