Carlo Gavazzi EM511 Energy Analyzers

Carlo Gavazzi EM511 Energy Analyzers are designed for 1-phase systems up to 240V L-N and current up to 45A. These analyzers offer enhanced readability due to the backlight display that ensures perfect visibility even in low light. The different sizes of the digits preceding and following the dot make the displayed values easier to read. Two mechanical keys make the page configuration and browsing very intuitive. Quick configuration is provided due to the configuration wizard that runs when the system is started up for the first time, allowing the user to commission the unit without errors in a matter of seconds. Carlo Gavazzi EM511 Energy Analyzers can be installed in any low-voltage switchboard with a rated current of up to 45A to monitor energy consumption, the main electrical variables, and the harmonic distortion.
