Basic power measurement accuracy is 0.1% of Reading plus 0.1% of Range. To measure these waveforms accurately, the WT300 uses high-resolution 16-bit ADC with a digitizing rate of 100 kS/s and a bandwidth from DC and 0.5 Hz to 100 kHz (20 kHz on WT110HC). Many of today’s power-conversion circuits use energy-saving switching techniques, which can cause highly distorted voltage or current waveforms with high harmonic content. All models have voltage ranges from 15 to 600 V RMS. This model has current ranges of 0.5 A to 20 A RMS. The WT330 is available as a two-element or three-element unit for applications on split-phase and three-phase circuits. The WT310HC is a single-phase high-current model with current ranges from 1 A to 40 A RMS.
The WT310 is a single-phase unit with the capability of measuring low currents from 50 ♚ up to 20 A RMS. The WT300 family consists of three models: WT310, WT310HC, WT330.
It is suitable for doing standby-power measurements, Energy Star and IEC62301 testing, and battery-charger and other low-level power measurements. It offers updated measurement functions, which will benefit engineers making basic electrical power measurements. This new addition to Yokogawa’s digital power analyzer product line is the 5th generation of its high-performance, low-cost product group. Yokogawa has announced its latest family of digital power meters, the WT300 Series.
