Carlo Gavazzi EM50 3-Phase Energy Analyzer

The new EM50 from Carlo Gavazzi is a DIN Rail mounted three-phase energy analyzer with an LCD display. It is equipped with a static output (pulse transmission), a relay output (alarm or remote control function) and Modbus RTU or BACnet MS/ TP port. EM50 is the perfect solution, especially in building and industrial automation where energy and main electrical variables monitoring is required.


  • Measure energy consumption and main electrical variables of single-phase, two-phase or three-phase loads.
  • Display single phase and total variables.
  • Transmit data via serial communication (Modbus RTU or BACnet MS/TP).
  • Transmit energy consumption via pulse output.
  • Transmit alarm and manage remote control via relay output.
  • Manage monthly energy log (current month and the previous two months).
  • Manage event log database (resets, terminal cover openings, configurations, alarms, etc.).


  • Flexible installation. EM50 is suitable for single-phase, two-phase, three-phase and wild-leg systems with different voltage levels used in USA and Canada.
  • Selectable communication protocol. Modbus RTU and BACnet MS/TP in the same unit.
  • Extended energy measurements. 4-quadrants reactive power and multi-tariff metering.
  • Easy navigation. The slideshow function automatically displays the desired measurements in sequence without having to use the keypad.
