With four differential voltage channels and four independent current channels, the award-winning Power Platform measures, analyzes and records power quality, harmonics and energy data simultaneously and continuously. Unique to the PP4300 are interchangeable TASKCards that expand the capabilities of the instrument within the same mainframe. TASKCards can transform the PP4300 from a single-phase troubleshooting tool into a full three-phase instrument for advanced power quality management or specific analysis such as inrush or fault recording.
