Precise measurement and data storage
Shelly Pro 3EM-3CT63 allows you to measure voltage, current, active and apparent power for each phase separately. With 4-quadrant measurement, the meter works well in both standard installations and renewable energy systems. The data record is stored in the device's memory for 60 days, and a built-in real-time clock ensures accurate event marking, even in the event of an Internet outage.
Easy installation and operation
The device is designed for DIN-rail mounting and supports both single-phase and three-phase installations. Measurement is carried out using special current transformers, which allows for non-contact reading of energy consumption. With the ability to work with the Shelly Pro Add-on Module (not included), you can control external contactors for automatic load management.
Home and business applications
Shelly Pro 3EM-3CT63 is an excellent solution for both homeowners and businesses. In home applications, it can be used to monitor the energy consumption of electric vehicle chargers, photovoltaic systems or the entire household. In business, it will prove useful for managing power consumption in commercial buildings, manufacturing plants and data centers, helping to optimize energy costs.
Advanced integration and automation
With support for KNX, Modbus, MQTT and WebSocket standards, the Shelly Pro 3EM-3CT63 can be easily integrated into building management and smart home systems. The ability to export data in CSV and JSON formats makes it easy to analyze energy consumption, and script support allows for customized automation tailored to individual users' needs.
Free Shelly Smart Control app
Shelly Smart Control is a free app that allows you to fully manage Shelly devices, monitor energy consumption and control costs in real time. With a clear interface, you can track the performance of individual devices, create automations and receive notifications of energy anomalies. The app works on smartphones and computers, and access to Shelly Cloud allows you to remotely control your installation from anywhere.
