Yokogawa has introduced its new WT300 series of digital power meters – the fifth generation of Yokogawa’s compact digital power meters – instruments that measure the power consumption of electrical equipment thus ensuring that high standards of energy efficiency and conservation are maintained.
Combining accurate and reliable power measurement over a wide power range, the new instruments will help developers and manufacturers of electrical equipment (ranging from domestic white goods to lighting systems and air conditioning equipment) to ensure that their products comply with emerging IEC and EN standards and increasingly complex and stringent specifications on energy efficiency.
The new instruments include a basic accuracy of 0.1% of reading, guaranteed accuracy over the entire measurement range (from 1% to 130%), a wide measurement range from standby power levels of a few milliamperes up to the 40A currents used in induction cookers, and flexibility to enable users to target different technical and commercial applications.
This includes a range of communications interfaces, allowing the WT300 series to be integrated into laboratory test benches or automated test set-ups on production lines. USB and GPIB or RS232 is fitted as standard, and Ethernet is available as an option.
In addition to standard power measurements, the new meters offer a wide range of harmonic measurement capabilities and also include a bandwidth of DC and 0.5Hz to 100kHz (up to 20kHz for 40A on the WT310HC), plus an auto-range function for measurement and integration.
Software is also available for testing equipment compliance to industry energy saving standards such as IEC 62301 Ed2.0 and IEC 62018 for standby mode equipment or for dealing with waveforms having a crest factor of five or more.
Yokogawa’s own European standards laboratory in the Netherlands also helps ensure guaranteed accuracy of the power meters.
