Power Analyzer PW8001 Hioki


The PW8001 sets a new benchmark for complete power analysis solutions with Hioki being the only manufacturer that offers industry-leading power analyzers and a wide portfolio of high-accuracy current sensors both developed and manufactured by Hioki. This enables to align their performance and results in more accurate and stable measurements from DC to high frequencies and low power factor measurements thanks to functions like the automatic phase shift correction.

Upcoming industry challenges are anticipated with the ability to measure even large currents at voltages up to 1500 V, 15 MS/s sampling rate and multi-channel measurement target applications using SiC/GaN semiconductors from automobile electrification, smart grids and reactors to renewable energy supply sources.
