CLAMP ON SENSOR 9272-05

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)

9272-10	20/200 A AC, PL23 terminal
9272-05	20/200 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.

CAT III 600 V
Key Features

• Superior low frequency and phase characteristics suitable for testing the current and power of inverter control devices
