Hioki Launches Power Analyzer PW6001

Hioki is pleased to announce the launch of the Power Analyzer PW6001.

The PW6001 delivers world-class measurement accuracy, a broader range of measurement frequencies than legacy and existing models, and a high level of stability thanks to improved noise resistance. The newly designed instrument also provides waveform analysis functionality and up to 12 measurement channels, a range of capabilities that befit the new model''s status as Hioki''s flagship power meter.

DEVELOPMENT BACKGROUND

While power analyzers have traditionally been used primarily to conduct power measurement in order to reduce the power consumption of electrical equipment such as household appliances and audiovisual devices as part of a larger effort to conserve energy, today they are used increasingly to measure energy conversion efficiency.

One example of an application in which energy conversion efficiency is measured is the analysis of the motors used in electric vehicles (EVs) and hybrid electric vehicles (HEVs). These motors are driven by batteries and controlled by an inverter to facilitate efficient operation. It is possible to calculate the energy conversion efficiency of this setup by measuring power between the battery and inverter on the one hand and between the inverter and the motor on the other and then comparing and analyzing the resulting values.

Apart from the EV and HEV world, there is also increasing demand for energy conversion measurement of devices such as power conditioners used in solar power installations and wireless power supply systems.
