The Yokogawa WT500 is a sophisticated power Analyzer with fast acquisition rate ideal for analyzing harmonics to the 100th order and transients. The WT500 can display inputs as waveforms, trends and in vector or bargraph format. Versatile integration functions such as active power (WP), current (q), reactive power (WQ), and apparent power (WS), and measurement of bought and sold watt hour. The Yokogawa WT500 can display, analyze and evaluate your power, making it an indispensable tool for Green IT, Energy Star and CO2 reduction.

The Yokogawa WT500 is designed for small current measurement in energy-saving equipment, as well as evaluating currents for large-sized loads. The WT500 works with voltages ranging from 1.5 V up to 1000 V, supporting a wide range of applications. Because it can accept signal inputs for up to six phases, a signal WT500 unit can measure I/O signals on inverters.

Yokogawa WT500 Features:

  • Simultaneous measurement of DC and AC signals
    Evaluation of DC/AC signal conversion technology is critical in the renewable energy market. With input from 2 or more elements, the WT500 can measure DC and AC signals simultaneously and calculate input-to-output efficiency.
  • Separate integration functions for charge/discharge and bought/sold power
    The WT500 is equipped with integration functions that can not only evaluate charge and discharge current such as from secondary cells, but also bought and sold power in photovoltaic power generation systems.
  • Saving measured data directly to USB memory
    Measured data can be saved in CSV format directly to USB memory.
  • Easy setup with cursor keys
    Menu-type screen offers intuitive setting.
  • Simultaneous measurement of normal data and harmonic data with the harmonic measurement, /G5 option
    RMS voltage, RMS current, power values, and harmonic components up to the 50 order can be measured simultaneously.
