Hioki Clamp On Sensor 9272-05 for Inverter Current Testing
The Hioki Clamp On Sensor 9272-05 is engineered for professionals who require accurate AC current measurement in low-frequency applications such as inverter control devices, motor drives, and power electronics systems. Built on Hioki’s proven current sensing technology, this sensor delivers exceptional amplitude and phase accuracy, making it a reliable choice for power and efficiency evaluation.
Wide Frequency Measurement
With a frequency range spanning from 1 Hz to 100 kHz, the Clamp On Sensor 9272-05 supports detailed waveform monitoring, harmonic analysis, and FFT analysis. This wide bandwidth allows engineers to capture both fundamental and higher-order frequency components commonly found in inverter-driven systems. Its superior low-frequency characteristics ensure stable measurements even in applications where conventional sensors struggle with phase shift and signal distortion.
Accurate Power Analysis
Accurate phase alignment between voltage and current is critical when evaluating power and efficiency. The 9272-05 provides excellent phase accuracy, particularly in the 45 Hz to 66 Hz range, enabling precise power calculations when used with compatible Hioki power analyzers. The sensor outputs an AC voltage signal proportional to the measured current through a compatible sensor unit or analyzer, ensuring clean and consistent data acquisition.
Safe and Flexible Integration
Rated for CAT III 600 V environments, the Clamp On Sensor 9272-05 is suitable for industrial and laboratory settings. It features a large 46 mm core diameter, allowing it to clamp easily around conductors in control panels and power distribution systems. While the sensor cannot operate independently, it integrates seamlessly with Hioki power analyzers, current units, and Memory HiCorders, providing flexibility across different test setups.
Applications
Common applications include inverter current testing, motor drive evaluation, power quality analysis, and harmonic measurement in industrial equipment. Its selectable current ranges and wide compatibility make it a dependable tool for engineers focused on accurate AC current and power measurement.
