Featuring New Current, Voltage & Power Solutions for Industrial/Factory Automation Markets

SAN JOSE, CA – December 17, 2018 – NK Technologies has released the 2019 product catalog, which features performance data, sizes, specifications, and technical references for the company’s extensive portfolio of current sensing switches, transducers, transformers, and ground fault protection products. Interested parties may download the interactive PDF catalog here, or request a printed copy of at

Featured in the new catalog are recently-introduced products including:

AT/ATR-TH and DT-FD Current Transducers:

The AT/ATR-TH monitors three-phase loads, motors, machines, or buildings with a large triple-aperture solid-core design that allows for quick and easy installation. Transducer outputs are powered from an excitation voltage of 24 VAC or DC, or optionally 120 VAC, isolated from the monitored circuit. The DT-FD is a high voltage DC current transducer with a large sensing window and the ability to monitor circuits with voltages up to 1500 VDC.

ASP-FD and DS1-FD Current Sensors:
The ASP-FD allows two separate trip points to detect overcurrent and undercurrent conditions. The sensor outputs are dual, single-pole, double-throw relays, that can control either AC or DC circuits. The DS-FD monitors AC or DC loads: motor, crane, or welding equipment. The relay features a large aperture and solid-core design for quick installation. The relay output is isolated from the monitored circuit and can switch up to two amps up to 125 VAC, or two amps to 30 VDC.

AGT-FD and DG Ground Fault Sensors:
The AGT-FD detect faults to earth from 0 mA to 100 mA and produces an output signal of 0–10 VDC in proportion to the amount of current passing to ground. The output is equal to the RMS value of the earth leakage. The AGT-FD can also be used to measure and monitor any low value AC circuit current. The DG's one-piece, solid-core design allows for installation over wires

feeding loads to about fifty amps. The output relay will change state at factory setpoint between 5 and 50 mA of DC current to earth.

“The 2019 catalog showcases our newest products as well as enhancements and increased functionality of existing products,” said Philip Gregory, President of NK Technologies. “With more than 1300 cost-effective, high-performing models available, we offer one of the broadest and most innovative selections in the industry.”
