Description
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. CLAMP ON PROBE 3273-50.
| 3273-50 | DC to 50 MHz, 30 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
• Wide band: DC to 50 MHz (-3 dB)
• High S/N characteristic enables measuring ultra low mA-range current waveforms
• 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
