Continuous Waveform Recordings

Unique to the BLACKBOX Series!

The G4K fixed power quality analyzer is able to record and store all electrical waveform continuously for more than a year, with no gaps in the data. It calculates RMS, harmonics or any other value of waveform in post-processing including the calculation of more than 10,000 parameters. The G4K fixed power quality analyzer offers a clear and comprehensive picture of the conditions before, during, and after an event.
