CLAMP ON PROBE 3274

CLAMP ON PROBE 3274

Wide band DC to 10 MHz/150A AC/DC Current Probe for Oscilloscopes

REQUEST A QUOTE



Description

Hioki flat bandwidth current probes are best-in-class current sensors for use with Memory HiCorders and high performance oscilloscopes CLAMP ON PROBE 3274

The 3274 supports wide DC to 10 MHz bandwidth signals and 150A of continuous high input, and is ideal for capturing transient current signals from switching power supplies, inverters, and motor controllers.

3274 DC to 10 MHz, 150 Arms

Use optional power supply 3269 or 3273 to drive the current probe when power from the Memory HiCorder or oscilloscope is not available.

Key Features

• Even with the wide DC to 10 MHz frequency band, current waveforms up to 150 A can be directly observed in applications such as power device and power-on in-rush current monitoring

• Connects directly to oscilloscope BNC input terminal

• Connects directly to the Memory HiCorder to provide waveform monitoring

• An optional power supply is available for use with oscilloscopes that do not provide probe power
