Shelly Pro 3EM-400A
New generation three-phase energy meter
Shelly Pro 3EM-400A New generation three-phase energy meter
Shelly Pro 3EM-400 is a DIN rail mountable three-phase energy meter . Boosted with everything
the flexibility of gen2 firmware and LAN connectivity, provides professional integrators with options
additional for end customer solutions. Shelly Pro 3EM-400 reports the accumulated energy
as well as the instantaneous voltage , current and power factor per phase in real time .
Why shelly pro 3em?
Shelly Pro 3EM-400 is a DIN mountable three-phase energy meter with Wi-Fi and Wi-Fi, Bluetooth and LAN connectivity.
With an active energy measurement accuracy of 1%, Shelly Pro 3EM-400 can be used to monitor
the consumption of household appliances, company electrical circuits and office equipment individually.
It has 60 days of historical data on the device with 1 minute resolution for each stage. Also, his
scripting capabilities enable the execution of complex scenes and provide broader monitoring capabilities.
Industrial grade security
Shelly Pro 3EM-400 supports mTLS for MQTT , HTTP and secure outgoing WebSockets . Its industrial-grade security
allows direct connections to your cloud infrastructure, reducing the cost of implementing complex networks and VPNs.
Infinite use applications
Industrial plants : Shelly Pro 3EM-400 offers MODBUS support for voltage, current, power and energies.
You can accurately sample your energy consumption and instantaneous voltage, current and power values.
Our new firmware platform allows for a custom implementation that can send
report to your infrastructure at the rate of every 100 ms.
2-Way Energy Consumption Monitor : Monitor your home, office or factory and avoid expenses
surges or voltage drops that could damage your appliances and devices.
Shelly Pro 3EM-400 can calculate bidirectional consumption: energy produced and used for each of the three phases .
The device can be configured to measure three separate circuits of a single-phase electrical system. View the
quality of your electricity network in terms of active power, reactive power, voltage and power factor.
Local Control : Thanks to Shelly Pro 3EM-400's scripting capabilities and webhooks, you can now easily control
other Shelly or Wi-Fi devices on your local network. Use these features to set exact parameters for
the heating, cooling or charging of electric vehicles based on the photovoltaic production and do so
your devices to automatically reduce energy consumption. All of these work without using a cloud.
Monitoring and control of solar panels
Track the amount of energy your solar panels or wind turbines generate and save effortlessly.
Shelly Pro 3EM-400 provides real-time information on solar and wind energy system efficiency, as well as
historical data on how much energy was generated and consumed every minute for the last 60 days.
This helps you control the flow of energy , getting the most out of your solar panels and wind turbines.
To take it a step further, connect Shelly Pro 3EM-400 to your other Shelly devices and create scenes to trigger the
desired actions such as turning off appliances or sounding alarms.
Shelly devices are compatible with Alexa, Google Home, Android and iOS .
Together with the voice assistant , you can control Shelly devices using only your voice!
