Current Transducers

Average Sensing

‘AT’ Current Transducers from NK Technologies combine a current transformer and signal conditioner into a single package. The AT Series has jumper selected current input ranges and industry standard 4–20mA, 0–5VDC or 0-10VDC outputs. The AT Series is designed for application on ‘linear’ or sinusoidal AC loads. Available in a split-core case or two types of solid-core cases.

C Frequency Output

The ‘ATQ’ Series Current Transducers sense currents from 0 to 200A and provide a patented proportional frequency output of 0-5 kHz or 0-10 kHz for use with digital-only PLCs. Useful in applications where high resolution sensing or frequency counting is needed, the ATQ Series features a jumper-selectable input and a split-core enclosure for easy installation.

DIN-rail Current Transducer

The ‘AP/APR’ Series products from NK Technologies are an innovative family of split-core current transducers designed specifically for DIN-rail compatibility in automation and data logging applications. A large aperture, switch-selectable inputs/outputs, and isolation between primary and secondary circuits combine to enhance product usability, safety and performance. The AP/APR Series also features the patented PRIME technology which eliminates the damaging effects of core saturation due to continuous exposure to high input currents. Models from 10A to 400A and with 0-5V/0-10V or 4-20mA outputs are available as standard.

Hall Effect Technology

‘DT’ Current Transducers from NK Technologies combine a Hall effect sensor and signal conditioner into a single package for use in DC current applications up to 400A. The DT Series has jumper selectable current input ranges and industry standard 0–20mA, 4– 20mA, 0–3VDC, 0–5VDC or 0–10VDC outputs. Available in solid or split-core packages.

High Current

‘AT/ATR 3 & 4’ transducers from NK Technologies combine a high capacity current transformer and a signal conditioner into a single package for applications from 200A to 2000A. The AT version is Average Responding for use on linear (sinusoidal) loads. The ATR version is True RMS for use on distorted waveforms found in VFD or SCR outputs. Available in a solid-core case

Powered Transducers

The ‘ATP’ Series powered transducers from NK Technologies sense current from 0-200A and provide a proportional analog VDC or mA output. Powered by 120VAC or 24VAC/VDC, the ATP eliminates the need for costly control power transformers or rectification of voltages within a panel. Designed for applications on ‘linear’ or sinusoidal AC inputs, the ATP features jumper-selectable current ranges, a choice of industry-standard 4-20mA, 0-5VDC and 0-10VDC outputs, and split-core or solid-core enclosure styles

True RMS

‘ATR’ transducers from NK Technologies combine a current transformer and a True RMS signal conditioner into a single package. The ATR Series provides True RMS output on distorted waveforms found on VFD or SCR outputs, and on linear loads in “noisy” power environments. Available in a solid or split-core case
