What is a digital power meter?

The digital power meter is a high-precision digital virtual instrument suitable for measuring the power of 5~400Hz three-phase sinusoidal alternating current. Including 3 power units, the two-wattmeter method or the three-wattmeter method can be used to measure the three-phase voltage RMS, current RMS, frequency and active power.

The voltage and current measurement channels of the power unit of the digital power meter include 8 ranges. The signal measurement range is expanded through automatic seamless range conversion, and the nominal accuracy index can be met within the range of 0.4% to 100% of the rated input signal.
