Shipping Policy
Shelly Pro 3EM-400A is a Wi-Fi-operated DIN-mountable 3-Phase Energy Meter with Wi-Fi, Bluetooth, and LAN connectivity. With active energy measurement accuracy of 1%, Shelly Pro 3EM-400A can be used to monitor the consumption of any home appliances, electric circuits, and office equipment individually. It features 60 days of on-device historical data with a 1-minute resolution for each phase. Additionally, its scripting functionalities allow for the execution of complex scenes and provide broader monitoring abilities.
4-quadrant measurement
Measure capacitive and inductive load types of active imported and exported energies.
Accuracy class B (active energy)
Shelly Pro 3EM-400A has a measurement accuracy of 1%.
MODBUS support
Allows for easy and fast deployment in existing industrial installations.
Wi-Fi, LAN, and Bluetooth connectivity
Simultaneous Ethernet and Wi-Fi usage. MQTT, inbound and outbound WebSocket, UDP, mTLS support.
Power monitoring
Monitors mono-phase electrical systems with up to 3 points simultaneously. Fast notifications and at least 60 days of 1-minute records storage.
Scripting functionalities
Shelly Pro 3PM fully supports mjS scripting, allowing you to create further features and functionalities.
Industry-grade security
Shelly Pro 3EM-400A supports mTLS for MQTT, HTTP, and secure outbound WebSockets. Its industry-grade security allows for direct connections to your cloud infrastructure, reducing the cost of deploying complex networks and VPNs.
2-way energy consumption monitoring
Monitor your home, office, or factory, and avoid additional expenses or drops in voltage that can damage your appliances and devices. Shelly Pro 3EM-400A can calculate 2-way consumption: produced and used energy for each of the three phases. The device can be configured to measure three separate circuits of a mono-phase electrical system. View the quality of your electricity network regarding active power, reactive power, voltage, and power factor.
