Yokogawa-POWER ANALYZER (Model: WT500)

The WT500 Power Analyzer is a Mid Range product for single-phase and three-phase power measurements. It is designed into a compact half-rack size chassis which can also be double rack mounted. Standard features include a color TFT display and USB interface for communications and memory. The instrument has a basic accuracy of 0.1%, maximum inputs of 1000 Vrms, 40 Arms and a measurement bandwidth of DC to 100 kHz.

Key layout offers intuitive control

Cursor Keys Cursor keys can be used to move the on-screen cursor in four different directions. The cursor keys and SET key can also be used for making selections in soft menus. The WT500's menu structure is even more user-friendly than other models. RANGE Keys The RANGE keys can be used to set the voltage and current ranges. Quick intuitive range control is available by using direct keys. DISPLAY Keys DISPLAY keys can be used to switch between numerical values, waveforms, and other displays. The display format can easily be changed. SETUP Key The SETUP key can be used to enter various settings required for power measurement such as the wiring method and filters. FILE, IMAGE, and STORE Keys The keys related to data storage are located in the same area. Data can be easily stored to USB memory.

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.
• WT series for power evaluation of energy-saving equipment
  The WT series have been used as powermeters for Green IT, Energy Star, CO₂ reduction and other energy-saving equipment. The WT series-Including the WT500–supports your power evaluation needs.

Newly Designed Architecture

Intuitive control by using cursor keys in four different directions.
To reduce setting errors, menus display settings in order of relative importance in order.

Measured Value Direct Save Function

Two USB ports for peripherals are installed for direct data saving (up to 1 G byte) in USB memory at shortest intervals. The saved data can be opened in applications such as Excel.

A Variety of Display Formats

In addition to numerical data, the WT500 can display input signal waveforms and trends (time variation of numerical data).  Bar graph display and vector display are also available with the harmonic measurement (/G5) option.

*1 Waveforms of up to approximately 5 kHz can be displayed.
*2 Excludes single-phase models.
Split screen display for numerical values and waveforms is not available.
