Analyseur de paramètres réseau intégré à un transformateur - MTA36

MTA36 Power meter Integrated in a transformer. With a revolutionary design MTA36 combines the transformer measurement and the network analyzer in one equipment, with its communication possibilities create a easy to install and versatile device. MTA36 advantages Cost effective solution Reduces installation time Improve reliability of the network Split core technolgy Lora Communication Compact design Free wireless communications through Radio Frequency (RF) Up to 10,000 meters Easy access to network data from the control center

Compact Design up to 36 mm diameter wire

Quick and safe closure system alows to adjust the device to the wire up to 36mm diameter.



Split core technology - avoid unnecessary network outages during installation


4 available versions: deppending on communication and desired net

• LORA single-phase
• LORA three-phase (3P4W)
• RS485 single-phase
• RS485 three-phase (3P4W)

Up to 10,000 meters

The distance between the control center and the analyzers installation can reach 10,000 meters, which is a great advantage. The built-in module allows easy access from the control center to network data.
