2/6

The E650 directly connected I&C meters record

active and reactive energy consumption in all three-

phase four-wire and three-phase three-wire

networks.

Range

E650 meters are the answer to a wide range of

specific needs: from the reliable commercial meter

to the complex measuring device with comprehen-

sive additional functionality for sophisticated data

acquisition and flexible tariff control of large indus-

trial customers.

Communication

AT/CT-type meters are equipped with modular

communication units which provide the right choice

for the best data channel at all times. «Plug+Play»

modules also offer you full freedom of choice for

deployment of new communication technologies.

Installation support

The monitoring of voltage, current, demand and

power factor supports the installation.
