Description

Model No. (Order Code)

3273-50DC to 50 MHz, 30 Arms

Note: Use the Power Supply 3269/3272 for general measurements or when power is not available from the Memory Hicorder. When performing continuous measurements, be aware of offset voltage drift.

Hioki flat bandwidth current probes are best-in-class current sensors for use with Memory HiCorders and high performance oscilloscopes. The 3273-50 offers a wide DC to 50 MHz bandwidth and 30A of continuous input, and is ideal for capturing transient current signals from switching power supplies, inverters, and motor controllers.

 

 

Key Features

• Highly accurate observation across a wide band from DC to MHz
• Connects directly to oscilloscope or Memory HiCorder BNC input terminal *1
• High S/N characteristics enable the measurement of 10 mA order current waveforms (3273-50, 3276)

*1 Connecting the device’s metal BNC terminal to a Memory HiCorder’s plastic BNC terminal may damage the plastic terminal or cause it to become misshapen.
