WT500 Mid-Range Power Analyzer
Brand: Yokogawa Electric Corporation
The WT500 Power Analyzer excels at single- and three-phase power measurements.
Standard features include a color TFT display and USB interface for communications and memory.
The instrument has a basic power accuracy of 0.1%, maximum inputs of 1000 V, 40 A and a measurement bandwidth of DC to 100 kHz.
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.
