AC current probe "CWT"
Easy to use with a thin and soft material! Current probe for power electronics development.
High-frequency 50MHz compatible! Rogowski coil type current probe The 【CWT Mini50HF】 is a Rogowski coil type current probe compatible with high frequency 50MHz (-3dB), manufactured by PEM (Power Electronic Measurements). The tip is detachable and made of a soft material that is thin and easily bendable, making it user-friendly and capable of accurately reproducing fast current waveforms, including sine waves, quasi-sine waves, and pulse waveforms. It is suitable for the development and analysis of power converters. 【Features】 ■ Detachable tip ■ Usable with digital voltmeters and power recorders *For more details, please refer to the catalog.
