EM511: the Single Phase Energy Analyser Series with Modbus RTU or M-Bus from Carlo Gavazzi
October 31, 2023
The EM511 is a bidirectional 1-phase energy meter with a backlit 9-digit display and 0.001 kWh resolution
Carlo Gavazzi Automation, the international electronics group with activities in the design, manufacture and marketing of electronic equipment, now presents the new EM500 series 1-phase energy analyser.
The EM511 is a bidirectional 1-phase energy meter with a backlit 9-digit display and 0.001 kWh resolution. Its energy measurement is bi-directional, thus enabling the separate measurement of imported and generated energy.
The EM511 analyser reduces commissioning time thanks to a quick setup procedure. In addition to energy meters, electrical variables and total harmonic distortion, the EM511 provides useful information for the maintenance team, such as run-hour meters and total operating time.
“Due to the 100 ms serial data refresh time, the EM511 is the ideal solution for storage applications, where a fast reaction is required to avoid feeding the grid when it is not allowed or to manage and optimize energy flows.” Andrea Bernardi, International Product Manager, says. “With this launch we also aim to integrate the EM511 with the successful EM100 series, especially for the most innovative applications in the Energy and Building efficiency industry. At the same time we are enlarging the EM500 series, providing additional meters suitable for integration into our energy management monitoring solution, without the need of writing new drivers.
Andrea Bernardi, International Product Manager
Developed in our competence centre in Italy, the EM511 series has been specifically designed to meet the requirements of energy analysis in Industrial and Building automation energy efficiency applications, for cost allocation and power metering.
