Thanks to the new range of EMDX³ electricity meters, multi-function measuring units, the CX³ EMS system or the DMX³ and DPX³ MCCBs incorporating measurement functions, Legrand has developed a smart infrastructure for displaying information on active and reactive power consumption, voltage disturbance, harmonic distortion, etc. according to the type of building.
EMDX³ multi-function measuring units record the energy consumed by the various circuits, measure the electrical values (current, voltage, power, etc) or analogue values (temperature) to check the installation is working properly. They monitor energy quality by analysing harmonics and measuring reactive energy.
They also communicate the values measured to supervision or energy management systems, in order to optimise the consumption and energy quality of electrical circuits in commercial and industrial environments.
By measuring your electricity consumption, you can:
-Become more aware of your consumption
-Adopt a constant operation regime to smooth out consumption over time
-Identify potential savings and implement actions and solutions to cut your consumption.
Thanks to the new range of EMDX³ electricity meters and our supervision solutions, it is possible to analyse consumption data and improve processes. It is also possible to manage multi-site electrical installations remotely or locally using a smartphone, tablet, or a PC.
The new EMDX³ electricity meter measure and display values such as total active energy, total reactive energy, partial active energy, active power, reactive power, apparent power, average active power, the maximum value of the average active power, current, cottage, frequency, the power factor, the running time (per tariff) per single-phase or three-phase circuit downstream of the electricity supply company’s metering.
EMDX³ electricity meters can be used to display consumption locally, in the distribution board or remotely via the internet.
They have two types of output that allow them to be integrated with a smart system: RS 485 Modbus or pulse.
The communication function makes it possible to:
-Centralise consumption
-Reproduce electrical values remotely via web servers.
The phase and neutral terminals have the same dimensions and are offset to make wiring easier.
Three-phase meters can be used to display phase sequences to ensure they are connected correctly.
All the meters have a built-in 120 0hm termination resistor on the RS 485 line, which can be configured in programming mode.
