Description

Multifunction meters displays all the installation’s electrical parameters.

The Nautil 920 multifunction meter displays all the network’s electrical characteristics. It also enables:

  • monitoring of electricity consumption for energy efficiency applications,
  • remote monitoring of parameters via an automaton or supervision system.

The Nautil 920 control unit is intuitive to use. All parameters are easily accessible via the direct access keys on the front of the device. The bar graphs show you the load on your installation at a glance.

This multifunction meter communicates via Modbus RS485 or pulse and is suitable for all industrial and tertiary installations. It is generally installed on main LV boards, TDs or TGSs.

One product, multiple communications

As standard, the control unit is equipped with a pulse output and a Modbus RS485 output.

The pulse output allows you to report energy consumption to an automaton. For complete analysis and supervision of your electrical installation, Modbus RS485 communication makes all the network parameters accessible via a BMS.

Technical support

Our network expert can offer you a support service for uploading information to a web page.

Wide backlit display

The wide backlit display makes the values easy to read. The bar graphs for the 3 phases quickly provide information about the electrical installation (balancing, etc.).

In addition, being able to directly read the cos phi means that a capacitor bank can be sized if necessary.
