Industrial security level
The DIN-mountable 3-phase energy meter Shelly Pro 3EM 400A supports mTLS for MQTT, HTTP and secure outbound web interfaces. With its industrial-strength security, you can connect directly to your cloud infrastructure, reducing the cost of deploying complex networks and VPNs.
Industrial installations
The device brings MODBUS support for voltage, current, power and energies. You can get accurate readings of energy usage and instantaneous values of voltage, current and power. Our new software platform enables a custom application that can notify your infrastructure as fast as every 100 ms.
Bilateral monitoring of energy consumption
Keep an eye on your home, office or factory and avoid extra costs or power cuts that could damage your equipment and appliances. The Shelly Pro 3EM-400 can calculate two-way consumption: energy produced and energy consumed in each of the three phases. The instrument can be configured to measure three separate circuits in a single-phase power system. See the quality of your electricity network in terms of active power, reactive power, voltage and power factor.
Local governance
With Shelly Pro 3EM-400’s scripting features and web shortcuts, you can now easily control other Shelly or Wi-Fi devices on your local network. Use these options to set precise parameters for heating, cooling or electric car charging based on solar power generation, and let your devices automatically reduce energy use. All of this works without using cloud services. The product is also available on hire purchase.
