Wi-LEM: PLUG & SAVE!
The Wireless Local Energy Meter (Wi-LEM) is a complete sub-metering
network that is fast and easy to install. The Wi-LEM family
consists of:
， Energy Meter Nodes (EMN) - an assembly of 1 to
3 current transducers with its signal processing module. They
can be deployed to measure energy consumption at any point
in the power cabinet and transmit the data.
， Mesh Nodes (MN) - a repeater linking various
Nodes. They enable wireless communications throughout a large
installation.
， Mesh Gate (MG) - a gateway managing the mesh
network. It provides data through serial interface to a PC.
Wi-LEM Key Benefits
Compared to traditional wired energy sub-meters network, Wi-LEM
brings key benefits at two levels:
，
Inside the cabinet installation
，
Network installation & commissioning
Inside the cabinet installation:
|
