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.
