CX-VFD Series

Solid Core AC Current Transducers CX-VFD Series

Solid Core AC Current Transducers


The Kele CX-VFD Series current transducers monitor line current for electrical loads such as pumps, conveyors, machine tools, or fans and output an anolog signal to represent the load current. The CX-VFD Series is loop-powered and requires 15 to 30 VDC to power the device. The CX-VFD Series features True RMS current measurement suitable to measure complex waveforms such as those found in VFD controlled loads. They are also suitable for accurate measurement of phase angled controlled or time proportional SCR controlled load currents. The CX-VFD Series current transducers contain a precision RMS-to-DC converter circuit which will measure load current accurately for complex, distorted or noisy waveforms as opposed to ″average reading″ devices that will only accurately measure pure sine waveforms.
