PEM Rogowski coil CWT Mini50HF15 high-frequency 50 MHz flexible current probe 3000 A

Brand: PEM

Origin: UK

CWT Mini50HF device (SiC), with 50 MHz high-frequency (-3dB) bandwidth (100 mm coil) and 36 MHz (200 optional, conductor diameter 3.5 (2 kV)/4.5 (5 kV)
Overview
PEM CWT Mini50HF is a special version of the CWT MiniHF series.

       CWT Mini50HF is optimized for faster switching devices (such as SiC), with a 50 MHz high-frequency (-3 dB) bandwidth and a 100 mm coil, and a thickness of only 3.5 mm (2 kV peak damage).

    CWT Mini50HF main features:

  • Traceable calibration data (including certificate)

  • Non-contact measurement has no effect on the circuit under test

  • No magnetic material means excellent linearity

  • Fully isolated from DC current, enabling measurement of small ripple currents on large DC currents

  • Overcurrent range does not cause damage
