Supports a temperature range of -40℃ to +125℃! For the development and monitoring of power converters, etc.
The "CWT MiniHF" is an AC current probe capable of measuring in tight spaces. By using an electrostatic shielded Rogowski coil, it can accurately avoid 50/60Hz voltage. Additionally, the peak current can be customized up to 300kA. It can be utilized in various applications, including measuring switching current waveforms of power electronics devices, developing and monitoring power converters, and measuring small AC currents within large DC currents. 【Features】 ■ Electrostatic shielded Rogowski coil ■ Expanded HF (-3dB) frequency range - Expanded up to 30MHz (100mm coil), 23MHz (200mm coil) ■ Improved peak di/dt performance up to 100kA/μs ■ Temperature range: -40℃ to +125℃ ■ Peak current customizable up to 300kA *For more details, please refer to the PDF document or feel free to contact us.
