Carlo Gavazzi presents VMU-C, VMUC-Y and Em2 Server

October 28, 2015 - Carlo Gavazzi Inc. says it has a new line of modular monitoring systems for energy management. VMU-C EM is a data logger system for small to medium projects. VMUC-Y EM is a hardware data aggregator for medium to larger projects, and Em2 Server is a software solution for large projects. Together, they are designed to complement the Carlo Gavazzi line of energy maters and current transformers.

The VMU-C EM is a combination of hardware modules, whose primary function is to collect data from a network of energy meters and environmental sensors and then make this data available to end users utilizing industry standard methods, such as integrated web server, FTP, HTTP and Modbus/TCP data transfers. In addition to data management, the VMU-C platform can provide a relay output, SMS or email alarms and scalable pulse rate inputs, Carlo Gavazzi notes.

The VMU-Y EM is built upon the VMU-C EM hardware platform, with a primary function of aggregating data from a network of VMU-C EM data loggers in applications where support for more than 32 energy meters is required. Up to 10 VMU-C EM / 320 meters can be managed by one VMU-Y EM, the company claims.

The Em2 Server is provided as a Virtual Machine software appliance to be hosted either in a customer’s facility or remote server. Similar to the VMU-Y EM, the Em2 Server relies on the VMU-C EM for communication with energy meters. It aggregates data in large applications with up to 100 VMU-C EM loggers/3200 energy meters and provides web server function, Carlo Gavazzi says.
