EM50 Energy Analyzers can be used for single, two, and three-phase systems, as well as wild-leg systems. The wide voltage range of EM50 makes it suitable for use throughout North America. It can measure the most relevant instantaneous electrical variables and energy consumption with a high level of accuracy.


The EM50 can be used with standard current transformers, Rogowski coils, 333 mV current sensors, and 80 mA current sensors for Measurement Canada versions. It features both Modbus RTU and BACnet MS/TP communications in each model. Energy consumption can be transmitted via the pulse output, and remote control and alarm are transmitted via a relay output.


The EM50 Energy Analyzer can be used in any application where understanding energy consumption trends are required in order to allocate costs, to measure for improvements in energy efficiency or to monitor load behavior in a facility or even a multi-site company.
