WT2010/WT2030 Digital Power Meters

The WT2000 digital powermeter series has been designed with emphasis on basic performance (bandwidth, accuracy, response speed, and noise immunity) from the viewpoint of measurement of electrical quantities. The broad range of functions of these power analyzers enable them to be used in various fields of applications.

Wide bandwidth: DC, 2 Hz to 500 kHz
Supports a wide measurement frequency range which is essential for developing and evaluating inverter-driven products. Measures DC voltage, current and power, as well as AC voltage, current from 2 Hz to 500 kHz. (Measures AC power from 2 Hz to 300 kHz.)
- Digital sampling technology
Employs a 16 bit A/D converter and a 32 bit high-speed computation DSP to achieve an accuracy of 0.03% and a measuring speed of 36 items of data/250 ms.
- Excellent noise and common-mode voltage rejection
Make the WT2000 the appropriate power meter for accurate PWM inverter efficiency measurements.

- Power accuracy: 0.04% of rdg + 0.04% of rng
The instrument is designed for high accuracy, permitting low power factor and reactive power measurement. The measurement error at zero power factor is as low as 0.1% of rng (45 to 66 Hz), making it suitable for inspecting transformers.

- High-speed response: 36 measured values in 250 ms
The instrument can simultaneously measure and output a maximum of 36 items of data per 250 ms, enabling the acquisition time on computerized inspection and evaluation lines to be reduced and the measurement efficiency to be increased.
