Energy Manager: Energy supply optimization - All essential data at a glance


The Energy Manager is a highly flexible OEM product for measuring and visualizing the electricity used or generated in households and buildings. It can be configured individually by the user. Its modular design means that both the hardware and the software are customizable.


The standard model stores and processes the measured data directly on resp. through its on-board components. The electricity used or generated can be visualized on terminal devices which the customer will probably already have at hand such as smartphones, tablets, Smart-TV sets or PC. For external processing of the data, automatic data export functionality (FTP or e-mail) are available. OEM customers can also decide to connect to a web portal (web cloud or intranet).


The standard design offers a LAN, Wi-Fi or RS485 interface for data transfer. OEM customers have available 3 designs of the Energy Manager to choose from: LAN; LAN and RS485 or Wi-Fi; LAN, Wi-Fi and RS485.


For current measurement on separate circuits, the RS485 interface allows to connect up to 8 external ABB current sensors; if using an external power pack, you can increase their number up to 24 resp. 32 ABB. OEM customers can order sensors from different manufactures as well.
