The Shelly Pro 3EM-400A is the largest version of the Pro 3EM 3-phase energy meter with WiFi, Bluetooth and LAN connectivity, DIN rail mountable. With an active energy measurement accuracy of 1 %, the Shelly Pro 3EM can monitor the power consumption of home appliances, electrical circuits and office equipment. The device stores 60 days of historical data with a resolution of 1 minute for each phase. In addition, its scripting features allow for complex scenarios and wider monitoring possibilities.
With the enhanced flexibility of the Generation 2 firmware and LAN connectivity of Shelly products, it offers professional integrators additional options for end-customer solutions. Shelly Pro 3EM reports real-time accumulated energy and current voltage, current and power factor by phase.
Features:
- Measurement in 4 quadrants with multiple connection types: measures capacitive and inductive types of active input and output energy loads.
- Class B accuracy (IEC 62053-21) for active energy: the Shelly Pro 3EM has a measurement accuracy of 1 %.
- Ready for photovoltaics
- Phase sequence error detection* (option)
- Optical pulse display of energy consumption
- This product version includes 3 current meters for 400 A
- MODBUS support: allows easy and quick installation in existing industrial installations.
- Connectivity via WiFi, LAN and Bluetooth: simultaneous use of Ethernet and WiFi. Support for MQTT, incoming and outgoing WebSocket, UDP, mTLS.
- Power monitoring: monitors single-phase electrical systems with up to 3 points simultaneously. Fast notifications and data storage with 1 minute resolution for at least 60 days. Data is stored in non-volatile memory.
- Scripting features:Shelly Pro 3PM fully supports mjS scripting, allowing you to create additional features and capabilities.
- Industrial security: mTLS for MQTT, HTTP and secure outbound WebSockets are supported by Shelly Pro 3EM. Its industrial-strength security allows direct connections to your cloud infrastructure, reducing the cost of deploying complex networks and VPNs.
Shelly PRO 3EM - EXAMPLES OF USE
Industrial installations
Shelly Pro 3EM brings MODBUS support for voltage, current, power and energy. You can accurately measure your power consumption and the current values of voltage, current and power. Our new firmware platform enables customized implementations that can report as fast as every 100 ms to your infrastructure.
Two-way monitoring of energy consumption
Monitor your home, office or factory and avoid extra costs or voltage drops that can damage your appliances and devices. Shelly Pro 3EM can calculate bidirectional consumption: energy produced and energy consumed for each of the three phases. The device can be configured to measure three separate circuits of a single-phase electrical system. Assess the quality of your power grid in terms of active power, reactive power, voltage and power factor.
Local governance
Thanks to the scripting and webhook features of Shelly Pro 3EM, you can now easily manage other Shelly or WiFi devices on your local network. Use these capabilities to set precise parameters for heating, cooling or charging electric vehicles based on PV production and automatically regulate energy consumption. All of this works without the use of the cloud.
Monitoring and management of solar panels
Keep track of how much energy your solar panels or wind turbines are generating and save effortlessly. Shelly Pro 3EM provides real-time information on the efficiency of your solar and wind energy system, as well as historical data on how much energy has been produced and consumed every minute for the last 60 days. This helps you control the energy flow and get the most out of your solar panels and wind turbines. If you want to go one step further, connect Shelly Pro 3EM to other Shelly devices and create scenarios to trigger desired actions, such as turning off appliances or triggering alarms.
