The Ulys MCM is Chauvin Arnoux Energy's innovative solution for centralizing the measurement of multiple electrical feeders

The Ulys MCM offers the functionality of 18 three-phase electricity meters in a single product. 

The Ulys MCM has multiple RJ12 “quick connect” inputs for connecting its 18 electrical feeders in just a few minutes.

All the elements in the current measurement chain can be clipped on, from the product to the current sensors.

To be reliable, electrical metering and measurement require correct installation of the product and its accessories.

There are many sources of error: current transformer installed upside down or back to front, current transformer installed on the wrong phase in the case of a three-phase assembly, incorrect connection at the level of the product, etc.

When all the incorrect connections are added together, the active power measured may be reduced by 80% of its rated value, which is a problem when it comes to processing the data.

These errors can occur even more frequently when the equipment is installed in the electrical cabinets of industrial or tertiary sites, where conditions are difficult.

Chauvin Arnoux Energy is very familiar with the issues faced by its installer partners, and with the Ulys MCM provides a solution for correcting installations without having to rewire the measuring instruments and accessories.

How? By connecting to Ulys MCM Utility, Ulys MCM's operating software.

A current transformer has been positioned upside down or back to front? Change the direction of this current transformer in just a few clicks.

A current sensor has been positioned on phase 3 and not on phase 1? The software allows you to reassign a current measurement to the correct phase.

To finalize your approach, a complete Fresnel diagram allows you to confirm that your modifications have had the desired effect.

Guaranteed one-time wiring on your installation sites by choosing the Ulys MCM for your electrical metering and measurement projects!
