Carlo Gavazzi EM530 is an energy analyser connected through 5A current transformers for two- and three-phase systems up to 415 V L-L. In addition to a digital input, the unit can be equipped (according to the model) with a static output (pulse or alarm), a Modbus RTU communication port or an M-Bus communication port.
The Carlo Gavazzi EM530 supersedes the EM24 Energy analyser.
