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 the efficiency of the latest high-accuracy electrical devices and systems. The PW8001 features eight slots for power input units, all of which can be used in combination with the motor analysis function.
For the configuration of the PW8001, two types of input units are available and can be freely combined in one instrument according to 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 inverter motor drives, as well as accurate inductor loss measurements under load.
Excellent resistance to external noise of 110 dB at 100 kHz ensures accurate and stable results, even in close 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 rating of 1500 VDC CAT II. It is ideal for applications requiring less bandwidth, such as testing the efficiency of industrial motor drives using IGBTs, wind turbines, and PV power converters.
Combined with HIOKI’s extensive range of high-accuracy and high-bandwidth current sensors, probes, and direct connection current boxes, the PW8001 offers a comprehensive solution for reliable measurements across applications ranging from small electronic devices to large-scale power systems.
The PW8001 Power Analyzer and HIOKI current sensors are developed and manufactured by HIOKI, enabling advanced automatic phase shift correction. This function ensures accurate phase-angle measurements between voltage and current, even at high frequencies and low power factors.
The PW8001 also features the unique Power Spectrum Analysis function. Unlike traditional FFT analysis, which determines harmonics based on the fundamental frequency and limits the measurable frequency range, this function covers the analyzer’s entire frequency spectrum. Power Spectrum Analysis provides immediate visibility into high-frequency power, delivering valuable insights for improving system efficiency.
Advanced capabilities such as wideband harmonic analysis and motor analysis ensure precise and reliable power analysis for a broad range of applications in the power electronics industry, including the development of high-efficiency power converters, electric drivetrains, and electric 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 and discharging in electric vehicles. This feature delivers exceptionally fast updates without compromising measurement accuracy.
The optical link function enables two PW8001 Power Analyzers to be connected, increasing the maximum number of measurement channels to 16. It supports synchronized power measurements and efficiency calculations across multiple inputs while eliminating timing differences through synchronized sampling.
