Overview
The IWATSU SS-290 AC current probe is a practical conversion tool designed to solve your power electronics current measurement problems:
With high bandwidth and a large measurement range, combined with high-quality measurement specifications, it ensures your measurement requirements are met;
The thin, flexible sensing loop allows you to easily connect to the actual measurement object.
Main features of the SS-290 series:
The probe has a top coil diameter of 8.5mm, and the open-type coil eliminates the risk of breaking the measured circuit.
With a frequency bandwidth of 20MHz, it can observe high-frequency switching waveforms.
The current measurement range of 1200A~120,000A supports various current measurements, and because it does not experience magnetic saturation, large current measurements can be performed safely.
The probe operates in a temperature range of -40°C~125°C.
Withstands voltage up to 10KV.
