CWT Range of AC Current Probes

The CWT Rogowski current probe is suitable for measuring AC currents ranging from a few 100 milliamps to hundreds of kA from below 1Hz to >10MHz.

	CWT Standard The CWT is a state-of-the art wide-bandwidth ac current probe with typical bandwidths in the range < 1Hz to 16MHz. Robust coils in lengths from 300mm to >1m Insulation Voltage 10kV peak Current Ratings 30A to 600kA
	CWT Mini The CWT Mini is a state-of-the art wide-bandwidth ac current probe with typical bandwidths in the range < 1Hz to 17MHz. Two Miniature Coil Sizes (3.5mm or 4.5mm) Insulation Voltage 2kV or 5kV peak Current Ratings 30A to 600kA
	CWT Ultra Mini Maximum coil cross section of 1.7mm fits through the legs of a TO-220 semiconductor device. Bandwidth: f_H(-3db) 20MHz Coil Size (Max. 1.7mm Cross Section) Insulation Voltage 1.2kV peak Current Ratings 30A to 1.2kA
	CWT LF – Low Frequency AC Probe Extended low frequency cut-off to enable measurements of long duration pulses (10’s ms) such as capacitor discharge. Available with Standard or Mini Coil Insulation Voltage 2kV, 5kV or 10kV peak Current Ratings 60A to 300kA

Overview

These clip-around probes are non-intrusive, easy to install in confined spaces, have an isolation capability of up to 10kV and are not damaged by over-current surges.

The CWT is ideal for power electronic development work because it combines the easy-to-use thin, flexible, clip-around coil with an ability to accurately replicate fast switching current waveforms be they sinusoidal, quasi sinusoidal or pulsed.
