The Valhalla 2101 is a benchtop digital power analyzer that measures true power consumption across DC and AC sources from DC to 50 kHz. Twin 4½-digit LED displays provide simultaneous readouts of true power in watts and switch-selectable true RMS voltage or current, enabling rapid determination of efficiency, power factor, and load characteristics across three voltage ranges (30 V, 150 V, 300 V) and multiple current ranges up to 20 A direct measurement.
