IWATSU SS-286A-H high-temperature-40 to 150 deg 1200 A high-frequency Rogowski current coil probe 1.7 mm for SiC device GaN test

The SS-280AH series uses an open flexible coil with a maximum wire diameter of 1.7mm, capable of passing through pin tests, suitable for narrow and extremely fine spaces, with a coil length of 84mm. Compared with traditional current sensors, it is easier to install and use, allowing online measurement and monitoring of current.


The SS-280A-H series is basically identical in appearance to the SS-280A series, and the measurement range is also basically the same. The main difference is that the SS-280A-H series can withstand high temperatures up to 150°C.

It is the only Rogowski coil that can withstand temperatures above 125℃.

Main Features of SS-280A-H Series:

• The probe tip diameter is as thin as 1.7mm, allowing direct detection of TO-type MOSFETs and IGBTs used in power electronic devices such as switch-mode power supplies.

• Has a frequency bandwidth of 30MHz, allowing observation of high-frequency switching waveforms.

• The current measurement range is 30A~30000A, supporting various current measurements without magnetic saturation, making it safe for high current measurement.

• Temperature range for the probe: A-H model-40°C ~ 150°C
