Effects or Remarks

This world-class, high-precision, wide-bandwidth power meter has a measurement accuracy of ±0.06%and a maximum measurement bandwidth of 1 MHz. It can directly measure inputs up to 1000V, minutecurrents from the mA order, and large currents up to 30A.The WT3000 comes equipped with a large color TFT liquid crystal display, a feature lacking in thepreceding model, which can display various inverter input and output data on one screen. The WT3000can help designers boost the efficiency of their evaluations.The WT3000 measures inverter input signals (voltage, current, power, phase factor, frequency etc.) andoutput signals (voltage per phase, current, power and 3-phase voltage, current, power etc.), and it cancalculate and display input-output efficiency data. Enter the pulse or analog signal revolution speed andtorque, and the WT3000 can collect data on inverter efficiency and motor efficiency as well as totalefficiency data, which contributes to energy consumption reduction via efficiency improvements inproduct development

Motor control has become more complex with the development of electronic circuit technology; however, moreand more companies are testing motor and inverter control with higher precisions instruments in order toachieve high efficiency in light of energy efficiency and other social issues. The WT3000 Precision Power Meter can take up to 4 measurements simultaneously, allowing for data collectionof RMS voltage, RMS current, active power, reactive power, apparent power, frequency, total harmonic distortion(THD) and high harmonic elements up to the 100th order. The WT3000 is the best tool for improving efficiencywith tests of inverter input-output efficiency. With its motor evaluation functions, the WT3000 can verify voltage,current, and current fluctuation, as well as concurrently measure revolution speed and torque change. TheWT3000 contributes to the data analysis and measures in the efficiency improvement of the motor.
