Analog Devices Inc. CN0548 Isolated High Voltage Measurement Module is used for testing and evaluating power systems in industrial and communications settings. This testing often requires multiple voltage and current measurements. Individual supplies may be referenced to different grounds, have either positive or negative polarity or be galvanically isolated with respect to other power domains. Such scenarios necessitate either individual floating multimeters or multichannel meters with per-channel isolation, which are physically cumbersome and expensive.
