Shelly Pro 3EM-400 (with 3x 400A clamps)
The Shelly Pro 3EM-400 is the ultimate solution for all your energy monitoring needs. With three 400A clamps included, this device allows you to accurately measure the energy consumption of up to three separate circuits simultaneously.
With improved LAN connectivity and all the gen2 firmware flexibility, Shelly Pro 3EM-400 gives expert integrators more choices for end-user solutions. It can be used independently in a LAN or WiFi network, or it can be controlled by MQTT, HTTP, and WebSocket to access cloud home automation services. TLS is supported on all inbound connections.
In real-time, the device provides information on cumulative energy, instantaneous voltage, current, active power, and perceived power per phase. It keeps information in non-volatile memory that can be recovered every minute for up to 60 days.
If the Pro 3EM-400’s connection to an SNTP server is lost, its real-time clock will maintain the accurate time. As long as both the device and the automation system are connected to the same network infrastructure, the user can remotely access, configure, and monitor the Shelly Pro 3EM-400. The gadget contains an embedded web interface that may be used to change its settings, monitor, and operate the device. There is no internal relay in the device. A Shelly Pro Addon that is fastened to the Shelly Pro 3EM-400 allows for contactor control.
