Category:Clamp On Sensors

Description:
Hioki flat bandwidth current probes are best-in-class current sensors for use with Memory HiCorders and high performance oscilloscopes. 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.


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
