electrical network analyzer electrical network analyzer - EMU-3ea


  • Measured entity:

    for electrical networks, AC energy network, DC electrical network

  • Measured value:

    power quality, harmonic

  • Other characteristics:

    monitoring, compact, real-time, multi-parameter, sampling, RS485, modular, FFT


The EMU-3ea has been designed in modular housing, 1U (17,5mm wide) for DIN rail. It supports all current sensors (secondary at 1A or 5A, 0…333mV and Rogowski coils).
The built-in digital output allows connecting the status of an output to the status of a limit threshold, an alarm, etc.
The EMU-3ea is also provided with a RS-485 interface with Modbus protocol to consent the integration in supervision systems.
