UNIVERSAL CLAMP ON CT 9279

Model 9279-01
Model 9279: Not CE Marked
Insulated Wire

Hioki AC/DC clamp sensors are best-in-class devices for use with power meters, Memory HiCorders and high performance oscilloscopes. The 9279 is a DC to 20 kHz/500 A sensor, ideal for monitoring waveforms of switching power supplies, inverters, power conditioners, etc.

Key Features

Wide DC to 200 kHz frequency bandwidth
Minimal zero drift for stable, long-term measurements
For power lines and secondary side of inverters
650 A of continuous input
Use together with the Sensor Unit 9555-10 for high precision waveform monitoring and recording
Also pair with AC/DC clamp on power meters

Model No. (Order Code)

9279	Discontinued, 500 A AC/DC
9279-01	Discontinued, CE marked model, DC to 20 kHz, 500 A

Note: Model 9279-01 compliant to CE-mark requirements is available on special order.
Note: These products cannot be used alone. The optional 9555-10 is required in order to supply power and connect the clamp to a Memory HiCorder or other instrument. Products can be directly connected the Power Meter 3193-10 and 3390 (cannot use with the 3390-10).
