  • IWATSU SS-683/SS-684/SS-685 world-first 100 MHz high-frequency Rogowski current probe

IWATSU SS-683/SS-684/SS-685 world-first 100 MHz high-frequency Rogowski current probe

Brand: IWATSU

Origin: Japan

SS-680 series closed-loop Rogowski coil, max 100MHz measurement bandwidth, Ls SIC.GaN test, saturation
Overview


The SS-680 series is a closed-loop Rogowski coil with a measurement bandwidth of up to 100 MHz, low Ls measurement, suitability for SiC/GaN testing, and no magnetic saturation limit.








                 
————————————————————————————————————————



    Main features of the SS-680 series:

  • Achieves a 100 MHz test bandwidth.

  • Suitable for measurement of high-speed power devices such as SiC and GaN.

  • Low Ls measurement is achieved through miniaturization and thinning of the probe tip.

  • Can measure up to 12000 A.

  • Because magnetic saturation does not occur, high-current measurement can be performed with confidence.

  • The sensor section is shielded and has good external-environment performance against external noise and other interference.

  • Probe applicable temperature range: -10 °C to +70 °C.

  • Maximum peak voltage 1.2 kV.
