SmartMDC is a concentrated metering equipment for power supply management with the ability to manage multiple users with single-phase, two-phase or three-phase service. Through a 3G wireless link, WiFi or an Ethernet connection, the system can be linked to provide the grid operator with all the information on the physical variables associated with the supply of each subscriber at a given moment in time, as well as historical records of the main variables associated with the service. Likewise, the equipment offers the possibility of performing actions such as cutting off, limiting or reconnecting the supply in a remote, verified and secure manner.
