Shelly Pro EM-50 DIN Rail Mountable Two-Channel, Single-Phase Energy Meter

Shelly Pro EM-50 (The Device) is a DIN rail mountable two-channel, single-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 EM-50 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. The Device has a built-in relay for contactor control.   Features 4 Quadrant measurement DIN rail mounting Current transformer connection External contactor control via built in dry-contact relay Optical pulse indication of energy usage Real-time clock Data logs Accuracy Class B (IEC 62053-21) Photovoltaic ready   Main applications Residential MDU (Multi Dwelling Units – apartments, condominiums, hotels, etc.) Light commercial (small office buildings, small retail/restaurant/gas station, etc.) Industrial (factories, power plants, water processing, refineries, etc.) Agricultural (farms, barns, silos, etc.) Government/municipal University/college TypeValuePhysicalSize (HxWxD):94x19x69 ±0.5 mm / 3.70×0.75×2.71 ±0.02 inWeight:63 ±1 g / 2.22 ±0.05 ozMounting:DIN railScrew terminals max torque:0.4 Nm / 4.43 lbinConductor cross section:0.5 to 2.5 mm² / 20 to 14 AWG (solid, stranded and bootlace lugs)Conductor stripped length:6 to 7 mm / 0.24 to 0.28 inShell material:PlasticColor:WhiteEnvironmentalAmbient temperature:-20 °C to 40 °C / -5 °F to 105 °FHumidity:30 % to 70 % RHMax. altitude:2000 m / 6562 ftElectricalPower supply voltage AC:100 – 260 V, 50/60 HzPower supply voltage DC:N/APower consumption:< 3 WOutput circuits ratingsMax switching voltage AC:240 VMax switching voltage DC:N/AMax switching current:2 ASensors, metersInternal-temperature sensor:YesVoltmeter (RMS):100 – 260 VVoltmeters accuracy:±1 %Ammeters (RMS via CT):0 – 50 AAmmeters accuracy:±1 % (5 – 50 A), ±2 % (0 – 5 A)Power and energy meters:Active and apparent powerActive and apparent energyPower factorMeasurement data storage:At least 60 days of 1 min data resolutionData export:CSV for PQ recorded valuesJSON format export through RPCRadioRF band:2400 – 2495 MHzMax.
