Dranetz DBPVFLEX PowerVisa Power Quality Analyzer

Dranetz DBPVFLEX PowerVisa Power Quality Analyzer

Equipped with 8 independent channels, the 3-phase PowerVisa is the only advanced power monitoring instrument to incorporate a color touch screen into its lightweight design. Automated setups provide instant detection of circuits and configurations, ensuring that the instrument is ready to successfully collect data. Users can select the length and mode of data collection, including troubleshooting, data logging, power quality surveys, energy and load balancing.
