1 EMDX 3 : Energy Metering A project to optimise quality and energy efficiency must include metering Metering upstream identifies the critical points and ensures optimum targeting of the actions to be taken, and downstream to monitor the effects and control any drift. Legrand EMDX³ metering range will naturally have a place in distribution boards. EMDX 3 metering control units All the essential parameters of the installation on DIN rail or on the door : - Active and reactive energy - Operating time - Power factor - Harmonic distortion - Programmable alarms 80 EMDX³ unit on DIN rail EMDX³ unit on door EMDX³ units on doors provide a large size display and their capacity can be increased with extension modules.

2 Eco-design a voluntary approach The Legrand group has been taking environmental problems into account since 00. This approach is based on international standards for the objective measurement of the environmental impacts of products in terms of both consumption of resources and pollution. Legrand publishes these reports in the form of PEP (Product Environmental Profile) sheets. Remote supervision and viewing With the Legrand communication interfaces (RS 485, IP), supervision software and Web servers, measurements can be centralised and displayed remotely on a PC, tablet or smartphone. EMDX 3 electricity meter on DIN rail EMDX³ meters installed in secondary distribution boards can be used to monitor consumption per building, per floor and per application.
