Emonio P3 Energy meter

The technology
of our Power Measuring Device

Emonio P3 is developed by energy consultants and electricians specifically for flexible application in different measuring environments. It records load curves of any device in any required measuring cycle. Receive measurement data of consumers by the split second. Installation does not require interruption of the power supply.

Simple installation of the power measuring device

Emonio P3 can be configured on-site either by app or browser using either your laptop, smartphone or a tablet that connects via the integrated WiFi. The transmitted data is encrypted using the  TLS 1.2 protocol. Emonio P3 has been certified by TÜV Nord according to DIN EN 61010-1 with regard to electrical safety.

Interruption-free measuring of power consumption

Emonio P3 uses flexible rogowski coils or foldable current transformers (CTs) for interruption-free measuring of the current intake. There is no limit to the number of main and sub-distributions or systems that can be measured. The flexible rogowski coils als allow for measuring conductors that are difficult to access.

Voltage supply and voltage measuring

Emonio P3 uses magnetic tips or crocodile clips/tips to connect to and measure the voltage. The voltage probes also provide the necessary voltage so no further power source is necessary. The performance data is calculated precisely from the voltage (U) and the current (I), which are then used in the calculations of each phase.

Variable recording time:

The possible recording time varies depending on the choice of recordable data and the measurement cycle. The more data and the shorter the sequence, the less possible recording sequence per memory unit.

1/3 Easy Attatchment

With its magnetic back, the Emonio P3 sticks in any junction box.

2/3 Small and compact:

The Emonio P3 Energy Meter can be easily installed anywhere.

3/3 In use Worldwide

The Emonio P3 Energy Meter is primarily used to determine actual load profiles in systems and machines that are difficult to measure.
