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

To Be Discontinued

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.
