CWT miniature wideband current probe for ac current measurement. AC Current Probe 50mV/A, 120A, 32Hz-20MHz, LF 80Hz. CWT is ideal for power electronics development work because it combines an 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.
Applications:
- monitoring current waveforms for semiconductor switches
- development and servicing of power electronic equipment
- monitoring high frequency sinusoidal currents
- measuring fault currents or circuit breaker interruption currents
- measuring pulses of current
- measuring ac currents superimposed on large dc currents
- measuring harmonic current components
- measuring signal or earth leakage currents in 3-phase supply systems
Features:
- measurement range from 300mA to 300,000A
- typical bandwidths from 0.1Hz to 16MHz
- the DC offset is no greater than 2mV over the operating temperature range
- thin and flexible, ‘clip-around’ coil in lengths from 300mm to 1000mm
- CE marked
