The Shelly Pro 3EM is a 3-phase energy meter that can be mounted on DIN rail. The smart energy meter measures the energy consumption in your home and reports the energy (cumulative), voltage, current and power factor per phase in real time. 3 CT clamps are included with a capacity of 120A.
The Shelly energy meter has a measuring accuracy of 1% and stores all measured data for a period of 60 days and a progress per minute per phase.
The Shelly Pro 3EM can be used to measure both sides, so on the one hand your consumption and on the other hand the generation of power through solar panels.
The Pro 3EM can also be integrated into an existing MODBUS installation . The Shelly Add-on can also be physically attached to this product. For example, you can measure the humidity or temperature in your technical room.
The Pro 3EM cannot switch itself, but you can of course use the measurements it makes as input for a scene in which another Shelly device turns something on or off.
