Shelly Pro 3EM 3CT 63
Description
Shelly Pro 3EM-3CT63 (the Device) is a DIN rail mountable single or three-phase energy meter. Enhanced with all the gen2 firmware flexibility and LAN connectivity, it provides professional integrators with additional options for end-customer solutions. It can work standalone in a local LAN and/or Wi-Fi network, or it can also be operated through cloud home automation services through Modbus, MQTT, HTTP, and WebSocket. All inbound connections support TLS.
The Device reports accumulated energy as well as instantaneous voltage, current, active, and apparent power per phase/channel in real time. It stores data in non-volatile memory that can be retrieved for a period of up to 60 days in 1-minute intervals.
The Device has a real-time clock to keep the correct time if the connection to an SNTP server is lost.
Shelly Pro 3EM-3CT63 can be accessed, set up, and monitored remotely by the User, as well as the Device can access and communicate with an automation system, as long as they are in the same network infrastructure.
The Device has an embedded Web Interface which can be used to monitor and control the device, as well as adjust its settings.
⚠NOTICE! The Device does not have a built-in relay. Contactor control is provided using a Shelly Pro 3EM Switch Add-on attached to the Shelly Pro 3EM-3CT63.
