Current Transducers

Description

NK Technologies introduces ATPR “E-Out” Series AC Current Transducers. ATPR current transducers combine a current transformer with a true RMS signal conditioner in a single package. This enables the ATPR series to produce a 0-5 or 0-10VDC RMS output on distorted waveforms located in the output of variable frequency drives, phase angle fired heating controls, and on linear loads in “noisy” power environments. 

“The ATPR series provides true RMS sensing, meaning output is proportional to the current flowing in the circuit even with high distortion or harmonic loads,” says Philip Gregory, President, NK Technologies. “Field selectable ranges minimize inventory requirements and easily accomodate changes in load conditions, and a split core housing simplifies installation – users simply release the latch and snap it over the conductor. And the unit’s DC voltage output is ideal for data acquisition systems, panel meters or controllers with only voltage inputs available.” The ATPR series is a perfect solution for monitoring the output of variable frequency driven loads, even when in bypass mode. They can also be used to measure phase angle fired heating controls and other SCR controlled loads. These current transducers respond quickly to element failure by monitoring current instead of temperature, and accurately measure power supply and ballast input power.
