Yokogawa WT300E Digital Power Meter

  • Sample Rate: 100 kS/s
  • Power Bandwidth: 0.1 Hz-100 kHz
  • Resolution: 16 bit
  • Elements: 1-3
  • Accuracy: 0.15%

The Yokogawa WT300E Series Digital Power Meter is one of the most reliable and accurate power meters on the market. The successor to Yokogawa’s fifth generation of compact power meters, the WT300E series offers unmatched performance for a variety of applications in manufacturing, quality control and Research & Development. This device is easy to use and provides accurate measurements for both AC and DC parameters.

The WT300E series is particularly suitable for conformity testing of uninterruptible power supplies (UPS), developing household appliances, and performing Energy Star and SPEC tests. Its exceptional performance at low power allows you to test devices according to standards such as IEC62301 and EN50564, ensuring that you always meet the most stringent energy efficiency requirements.

With more than 30 years of experience in power measurement technology, Yokogawa offers the ideal solution for a wide range of applications with the WT300E. This power meter can seamlessly perform both harmonic measurements and integrations without changing the measurement mode. With the ability to measure and store up to 200 parameters simultaneously using the WTViewer FreePlus software.

Wide range of functions

The WT300E series offers a wide range of functions to meet the needs of different industries. With advanced filtering capabilities, such as the line and frequency filters, unwanted noise and harmonics are filtered out of the measurement results for accurate measurements of the fundamental waveform. In addition, automated speed control of the measurement range enables continuously accurate measurements even with fluctuations in the input signal.

With a frequency range of DC to 100 kHz and an accuracy of ±0.15% at 50/60 Hz, the WT300E series offers exceptional precision over the entire measurement range. This over a voltage range of 15V to 600V in 6 ranges. In current measurements, depending on the model, we have access to 12 ranges from 5mA to 20A and even a model with 40A RMS, making it suitable for measuring both low standby power consumption and high currents in induction stoves.

Models

The WT300E series offers several models to meet specific needs:

  • WT310E: With one input element and suitable for both AC and DC measurements with a range up to 20A.
  • WT310EH: With higher current capacity up to 40A.
  • WT332E: With two inputs for simultaneous measurements of multiple phases.
  • WT333E: With three inputs for full three-phase measurements.

One of the key advantages of the WT300E series is its fast update rate of only 100 ms, which ensures fast and accurate test cycles, making it ideal for manufacturing environments where time is a critical factor. In addition, the device offers flexible connectivity options such as USB, RS-232, GP-IB and optional Ethernet connections, allowing you to easily capture and manage data via external devices.
