SS-680 series is a closed-loop Rogowski coil with measurement bandwidth up to 100 MHz, low-Ls measurement, suitable for SiC/GaN testing, and no magnetic saturation limitation.
————————————————————————————————————————
Key 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 by miniaturizing and thinning the probe tip.
Can measure up to 12000 A.
Since magnetic saturation does not occur, large-current measurement can be performed with confidence.
The sensor section is shielded, providing good resistance to external noise and other external environmental factors.
Probe head operating temperature range: -10°C to +70°C
Maximum peak voltage: 1.2 kV
