Overview
The CWT Mini and MiniHF are state-of-the art, clip-around, AC Rogowski current probes with a small form factor and virtually zero insertion impedance.
The New CWT MiniHF combines an innovative screened Rogowski coil providing excellent immunity to interference from fast local dV/dt transients or large 50/60Hz voltages and an extended 30MHz (-3dB) high frequency bandwidth for 100mm coils. The coil has a wide operating temperature from -40°C to +125°C and is available with 5kV peak insulation, 4.5mm thickness.
The CWT Mini features both improved high frequency and low frequency performance. The CWT Mini is available with a coil thickness of 3.5mm (2kV peak) or 4.5mm max (5kV peak).
The CWT range is ideal for power electronic applications, such as monitoring semiconductor switching waveforms or for measurements in electrically noisy environments. The easy-to-use thin, flexible, clip-around coil accurately replicates fast switching current waveforms be they sinusoidal, quasi sinusoidal or pulsed.
