Description
Hioki flat bandwidth current probes are best-in-class current sensors for use with Memory HiCorders and high performance oscilloscopes CLAMP ON PROBE 3275
The 3275 supports wide DC to 2 MHz bandwidth signals and 500A of continuous high input, and is ideal for capturing transient current signals from switching power supplies, inverters, and motor controllers.
| 3275 | DC to 2 MHz, 500 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 2 MHz frequency band, current waveforms up to 500 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
