Three phase indirect power meters using current transformers by EMU Metering - purchase now!

Are you and your customers often powered up? Then electricity consumption must of course also be properly tracked. How much energy is used in a particular time frame? Are there third-party quantities that must be delimited? Three phase transformer measurements by EMU Metering can answer these questions. This type of energy meter is calibrated in accordance with MID standards and effortlessly meets high demands. Thanks to different interfaces such as M-Bus, KNX, and LoRa, you can also access the electricity meters of the product series Allrounder, Professional and Professional II remotely. Let energy flow and trust in the high-quality three phase converter measurement devices and other products from the EMU Metering online store.

What interfaces are there for three power meter using CTs?

The three phase converter measuring device of EMU Metering is equipped with the following interfaces:

M-Bus
KNX
Modbus
LoRA
TCP/IP

For example, small and simple data packages can be quickly sent via the technology of a Long Range interface. M-Bus, on the other hand, requires additional software such as the M-Bus Center by EMU Metering. The consumption data for water, heat, gas, and electric meters can be easily exported via .csv files for this purpose. Both interfaces have in common that they facilitate transparent and traceable energy measurements via three phase converter measuring.

Which product series are available for three phase converter measuring devices?

In the online store of EMU Metering, the converter measuring devices for three phase electricity meters have the sonorous names Allrounder, Professional and Professional II. Let’s review the benefits and functions of the individual product series together.

EMU Allrounder - the jack of all trades

With the EMU Allrounder you are purchasing a versatile transformer-operated meter with many useful features. It has a so-called S0 pulse output and allows for multiple adjustments of the converter ratio. With the Allrounder, both high and low rates can be controlled. The accuracy class of this measuring device is B; which means that the max. deviation is 1 %.

EMU Professional - high-quality devices at the cutting edge of technology

The three phase energy and performance counters have a direct connection with 75 Ampere, which is operated using current transformers. EMU Professional belongs to the so-called smart meters, because it transmits recorded energy consumption via an interface to superordinate systems. It can help to reliably calculate high and low rates. Transformer measuring devices of the EMU Professional series are suitable for energy management according to ISO 50001, Minergie and self-consumption communities (ZEV).

The following data can be found in the LCD display:

Active and reactive energy (delivery/import)
Active, reactive, and apparent energy
CosPhi (performance factor)
Min./max. values

EMU Professional II - precise measurements

If you decide to purchase a three phase energy meter with transformer measurement from the product series EMU Professional II, you have access to a device that is has both MID and PTB-A 50.7 approval. It has a 100 Ampere direct connection, or a current transformer with 1 or 5 Ampere. For third-party quantity delimitation, the three phase transformer measurement devices of this series can also be used - thanks to the load profile memory and PTB-A 50.7-certified log book. Optionally, you will receive the EMU Professional II with M-Bus, TCP/IP, Modbus RTU or LoRa interfaces. It displays the same values as the predecessor EMU Professional. In addition to ISO 50001, Minergie, self-consumption communities (ZEV), third-party quantities can also be delimited reliably using three phase transformer measurements.

Which power meter suits your needs?

Essentially, you can distinguish between single phase and three phase energy meters. In addition, the three phase measuring devices are categorised into direct connections and indirect connections via a current transformer. The latter usually have interfaces that can be used to send the collected data to servers in the distance. Single phase measuring devices can be installed into almost any switch cabinet thanks to their sleek design. They are suitable for direct connections of up to 40 Ampere and have a S0 pulse output. Every model also has a built-in M-Bus interface.

EMU Metering offer a host of different powermeters for different purposes. Review our product range and experience it for yourself. Do you have any questions, suggestions or requests? Please contact us - we look forward to talking to you!
