Direct Current Measurement Element that Delivers a Wide Bandwidth and Superior Accuracy

Hioki benchtop power meters and power analyzers are best in class power measuring instruments for measuring single to three-phase lines with a high degree of precision and accuracy. The PW9100 is a direct AC/DC current measurement option for the PW6001 and 3390 series Power Analyzers that delivers wide bandwidth and high accuracy testing across 3 or 4 channels of input. The option is ideal for applications requiring direct input connections when testing the power conversion efficiency of motors, primary and secondary side of inverters, hybrid and electric vehicles, and renewable energy equipment. Key Features • World-leading measurement bands and accuracy • Wide-band DC to 3.5MHz, 50A AC/DC rated input • ±0.04% power accuracy in combination with PW6001 • 120dB CMRR (100 kHz) • Full-rack size suitable for test/evaluation benches • Current measurement option for PW6001/ PW3390/ 3390 POWER ANALYZERS

Model No. (Order Code)

PW9100-03 For the PW6001/PW3390, 3 ch
PW9100-04 For the PW6001/PW3390, 4 ch


The optimal device for testing inverters

For more reliable wideband high-accuracy measurements. Delivering a direct-coupled type current testing tool that brings out the PW6001 POWER ANALYZER's maximum potential.The existing direct-input type power meter can be replaced easily. Use two PW9100-03 devices (the 3ch models) for 6-channel measurements.
