Ideal for Measuring AC Current with Low Frequencies
such as Inverter Control Devices

Hioki current sensors are best-in-class devices for use with power
meters, Memory HiCorders and high performance oscilloscopes. The
9272-10/9272-05 are a 1Hz to 100 kHz AC current sensor ideal for
measuring low frequency equipment such as inverters.

Model No. (Order Code)

9272-1020/200 A AC, PL23 terminal
9272-0520/200 A AC, ME15W terminal

Note: This product cannot be used alone.
The optional Sensor Unit is required in order
to supply power and connect the clamp to a
Memory HiCorder or other instrument.
The clamp can be directly connected to a
compatible Power Meter, or Power Analyzers.

Key Features

• Superior low frequency and phase characteristics suitable for testing the current and power of inverter control devices
• Wide 1 Hz to 100 kHz frequency bandwidth perfect for harmonic analysis, FFT analysis and waveform monitoring (AC only)
