Carlo Gavazzi EM530 & EM540 2-/3-Phase System Energy Analyzers

Carlo Gavazzi EM530 and EM540 2-/3-Phase System Energy Analyzers are direct connection energy analyzers for two- and three-phase systems up to 415V and currents up to 6A (EM530) or 65A (EM540). The EM5x0 Energy Analyzers provide all the main electrical variables to identify any possible malfunction early and correlate the energy consumption with the hours of operation to plan maintenance and prevent failures. In addition to a digital input, the units can be equipped with a static output (pulse or alarm), a Modbus RTU communication port, or an M-Bus communication port. Features include a backlit LCD, an intuitive user interface with three mechanical keys, and a configuration wizard that runs on system start-up.
