  • Class: Class A



MYeBOX® is a range of portable analysers that can be configured from an app and/or a website to analyse and record electrical parameters, measure and record waveform transients and network quality parameters, as per the EN 50160 standard. The information is accessible remotely from the app and/or website. MYeBOX® measures and records electrical parameters in single-phase, two-phase or three-phase installations (with and without a neutral).
The app/website is connected to the device to display the measured data in real time, fully configure the device, start or stop the data recording, send the recorded data to the MYeBOX® Cloud platform, and even access the data from the memory to view it graphically or in table form. The remote connectivity lets you analyse the measured data from anywhere. The recorded data can also be sent to a data repository for further analysis in PowerVision Plus. The device can be configured locally using the capacitive keyboard and the on-screen menu options.

MYeBOX® 150 and MYeBOX® 1500 have the following features and functions:

  • 4 voltage measurement inputs (U1U2U3Un)
  • 4 current measurement inputs (I1I2I3In)
  • Measurement of the main electrical parameters
  • Measurement of network quality parameters
  • True RMS measurement (TRMS)
  • Measurement of consumption and generation (4Q)
  • Voltage quality event log, according to EN 61000-4-30
  • Transients log
  • Recording of the wave shape associated with the quality events and transients
  • Measurement according to EN 61000-4-30
  • Power supply is independent of the measurement
  • Recording of the wave shape for each recording period
  • LCD Screen
  • Capacitive keypad
  • Micro-USB port to download data
  • Automatic detection of clamps
  • Identification of phases with colours
  • Compatible with clamps with EEPROM
  • Recording of system events (EVA)
  • NTP synchronisation
  • Sending of alarms via e-mail
  • Wi-Fi communications (access point/terminal)

The MYeBOX® 1500 model also has:

  • 1 voltage measurement input Uref
  • 1 leakage current measurement input
  • 2 transistor inputs to centralise impulses / tariff / state
  • 2 transistor outputs for alarms
  • 3G/4G communications


MYeBOX can be used to:

  • Prepare complete studies of an electrical installation.
  • Analyse consumption, load curves, disturbances in the installation's voltage, display wave shapes, harmonics study or flicker measurement, among other options.
  • Perform audits and analyses remotely.
