The Pacific Power SCU-UPC32 is a programmable controller that transforms AC power sources into a 3-phase arbitrary waveform generator and precision metering system. It enables independent amplitude and phase control across all three phases while capturing output voltage and current at high resolution using a 12-bit A/D converter for detailed power analysis.
