Shelly Pro 3EM 120A
Device identification Device name: Shelly Pro 3EM Device model: SPEM-003CEBEU Device SSID: ShellyPro3EM-XXXXXX Short description Shelly Pro 3EM (The Device) is a DIN rail mountable 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 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 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 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 Addon attached to the Shelly Pro 3EM. Features 4 Quadrant measurement DIN rail mounting Multiple connection types: three phase or single phase installations Current transformer connection: non contact measurements for easy installation. Phase sequence error detection1 (option) Channel-to-channel calibration2 No load threshold3 Optical pulse indication of energy usage Real-time clock: stored data keeps correct timestamps even if the internet connection is interrupted.4 Data logs: up to 60 days of data stored on the device for later retrieval External contactor control: loads can be controlled based on device automation or scripts. Available with the addition of the Shelly 3EM Switch Add-on Accuracy Class B (active energy)5 Photovoltaic ready 1 The Device has phase sequence error detection circuits. This detection works on phase voltages and considers only the zero crossings. The regular succession of these zero-crossing events is Phase A followed by Phase B followed by Phase C. If the sequence of zero-crossing events is, instead, Phase A followed by Phase C followed by Phase B, then a phase_sequence error is reported when the Phase sequence error detection option is enabled. 2 At least 500 W load is required for each channel. 3 In case the total load for the three channels drops below 30 VA per channel the measured power level will be displayed, but no consumed energy will be accumulated to the energy statistics and a No load threshold notification will be displayed in the Device web interface and the mobile application. 4 Shelly devices rely on internet connection for device clock. In case of installation network requirement or service interruption, the built-in clock provides correct timestamps for records. 5 The Device has a measurement accuracy of 1%, based on internal design validation and testing. Main applications Residential MDU (Multi Dwelling Units - apartments, condominiums, hotels, etc.) Light commercial (small office buildings, small retail/restaurant/gas station, etc.) Agricultural (farms, barns, silos, etc.) Government/municipal University/college Simplified internal schematics Device electrical interfaces Inputs 4 line inputs on screw terminals: 3 L and 1 N 4 current transformer inputs: 3 for L current measurements and 1 for N current measurement Ethernet port 1 RJ45 connector ⚠CAUTION! Plug in or unplug the LAN cable only when the Device is powered off! The LAN cable connector must not be metallic in the parts touched by the user to plug in or unplug the cable. Add-on interface Shelly proprietary serial interface ⚠CAUTION! High voltage on the add-on interface when the Device is powered! Connectivity Ethernet Wi-Fi Bluetooth Each connectivity option can be enabled or disabled by the user. Safety features Internal temperature sensing and reporting Supported load types Resistive (incandescent bulbs, heating devices) Capacitive (LED light drivers, capacitor banks, electronic equipment, motor start capacitors) Inductive (transformers, fans, refrigerators, air-conditioners) User interface Inputs One tactile dome button Press briefly to toggle the state of the relay in the attached Shelly Pro 3EM Switch Add-on. Press and hold for 5 sec to activate Device AP. Press and hold for 10 sec to factory reset. Outputs LED indication Power: Red light if the power supply is connected. Wi-Fi (varies): Blue light if in AP mode. Red light if in STA mode, and not connected to a Wi-Fi network. Yellow light if in STA mode, and connected to a Wi-Fi network. Not connected to Shelly Cloud or Shelly Cloud disabled. Green light if in STA mode, and connected to a Wi-Fi network and the Shelly Cloud. The LED will be flashing Red/Blue if OTA update is in progress. LAN: Green light if LAN is connected. Count: Red light will be flashing when the Device is measuring energy according to settings with frequency dependent on the energy flowing through the measured circuit.
