The inventive architecture of Elspec multi-functional recorders takes power quality monitoring to a whole new level. Our meters provide the ability to record the waveform at sampling rate of 1,024 sample/cycle on-board for 1+ years in a continuous way. All our metering and recording solutions are supported by our multi-vendor power management software PQSCADA Sapphire. This combination provides the calculation of more than 5,000 power parameters from the recorded waveform for display and reporting purposes. Guarantee the availability of data for any event at any time.
