Detailed Description:
The HIOKI PW8001 Power Analyzer is a state-of-the-art measurement instrument designed for the most demanding power analysis tasks, providing precise measurement results when evaluating efficiency of latest high accuracy electrical devices and systems. The PW8001 has 8 slots for power input units, which all can be used in combination with the motor analysis function.

For the configuration of the PW8001, two types of input units are available that can freely be combined in one instrument according to the application requirements.

The U7005 High Bandwidth input unit offers ultimate precision with ±0.03% basic accuracy, a sampling frequency of 15 MHz, 18-bit A/D conversion and a maximum input voltage of 1000 VAC. It is suitable for applications such as efficiency measurements of SiC and GaN based inverters motor drives, and accurate inductor loss measurement of inductors under load. Excellent resistivity for external noise of 110 dB at 100 kHz, ensure accurate and stable results even in the proximity to high frequency power switching semiconductors.

For high-voltage applications, the U7001 input unit provides ±0.07% basic accuracy, a maximum input voltage of 1500 VDC, a sampling frequency of 2.5 MHz, 16-bit A/D conversion and a maximum voltage to ground of 1500 VDC CAT II. It is a suitable unit for applications which need less bandwidth, such as testing of the efficiency of industrial motor drives using IGBTs, or wind turbines and PV power converters.

Combined with HIOKI’s extensive lineup of high-accuracy and high-bandwidth current sensors, probes and direct connection current boxes, the PW8001 offers a unique and comprehensive solution for reliably measuring applications from small electronic devices to large-scale power systems.

The PW8001 power analyzer and the current sensors are developed and produced by HIOKI, making the advanced automatic phase shift correction function possible. This ensures accurate phase angle measurement between the voltage and current, even at high frequencies and low power factors.

The PW8001 offers the unique Power Spectrum Analysis function. While the traditional FFT function determines the harmonics based on the fundamental frequency, limiting the frequency range, this new function covers the entire frequency spectrum of the analyzer. The Power Spectrum Analysis function delivers quick visibility into the high frequency power, providing developers with valuable data for further system efficiency improvements.

Other advanced functions like wideband harmonic analysis, and motor analysis, ensure precise and reliable power analysis results for a wide range of applications in the power electronics industry, such as the development of high efficiency power converters, electrical drivetrains and electrical motors.

The 1 ms update rate enables high-speed data refresh, allowing precise detection and analysis of rapid power fluctuations, such as those occurring during battery charging or discharging in EVs. This feature ensures unprecedented updates without compromising on measurement accuracy.

The optical link function allows the connection of two PW8001 power analyzers to increase the maximum number of measurement channels to 16. It enables synchronized power measurements and efficiency calculation from multiple inputs, optimizing measurement setup and eliminating timing differences in data collection because the sampling of all inputs is synchronized.
