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 PW9100A is a direct AC/DC current measurement option for the Hioki 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.

The optimal device for testing inverters

Direct-coupled type current testing device

For more reliable wideband high-accuracy measurements.
Delivering a direct-coupled type current testing device that brings out the Hioki Power Analyzer's maximum potential. The existing direct-input type power meter can be replaced easily.

Use two PW9100A-3 devices (the 3 ch models) for 6-channel measurements.

Automatic detection capability for even greater convenience

Automatic current sensor detection by Power Analyzer PW8001

The PW9100A is equipped with a memory (I2C-EEPROM).
The PW9100A has a built-in highly accurate current sensor, which can measure current by direct connection.
When the current sensor is connected to the Power Analyzer PW8001, the phase correction data, rated current, sensor's model name, and serial number are automatically recognized by the instrument.

In the past, phase correction values had to be entered manually.
However, thanks to the automatic detection system of current sensor information, forgetting settings and typing errors are eliminated, allowing for more accurate power calculations.
