Carlo Gavazzi EM50 Energy Analyzer

Carlo Gavazzi EM50 Energy Analyzer is a three-phase energy analyzer with an LCD display for DIN-rail mounting. EM50 is designed for applications requiring the consumption trend to allocate costs, measure energy efficiency improvements, or monitor load behaviors. Carlo Gavazzi EM50 Energy Analyzer is fully compatible with the Universal Windows Platform (UWP) web-based monitoring system. The analyzer has a static output (pulse transmission), a relay output (alarm or remote control function), and a Modbus RTU or BACnet MS/TP port. EM50 manages direct voltage connection up to 600V L-L or employing voltage transformers. The current measurement is carried out via a 5A current transformer, 333mV or 80mA (Measurement Canada only) current sensor, or Rogowski coil.
