New 2018 Product Catalog Available from NK Technologies
Current, voltage and power solution products for industrial & factory automation markets
SAN JOSE, CA – January 2018 – NK Technologies announces the publication of its 2018 catalog, which includes performance data, sizes, specifications and technical references for the company’s extensive line of current sensing switches, transducers, transformers, ground fault protection and other products.
Innovative new products featured in the catalog include the ASP-FD Current Operated Switch, which allows two separate trip points detect overcurrent and undercurrent. Sensor outputs are dual, single-pole, double-throw relays that can control either AC or DC circuits. The new APT-TH Power Transducer is a one-piece solution for measuring power – no external current transformers needed. It monitors watt consumption of three-phase loads and provides an analog signal proportional to the active power consumed by the monitored load. The three current-carrying conductors pass through the three windows of the top section and the matching voltage input at the terminals.
“The 2018 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 1,300 cost-effective, high-performing models available, we offer one of the broadest selections in the industry.”

NK Technologies Introduces New VTU-DIN Series: True RMS AC or DC Voltage Transducer in Space-saving Design
SAN JOSE, CA – NK Technologies introduces the VTU-DIN Series, a high-performance True RMS transducer for sensing voltage in single, three-phase or DC installations. The VTU-DIN measures 0-15 to 0-600 V with an industry standard output proportional to connected voltage in AC circuits with sinusoidal or non-sinusoidal (variable frequency) applications or DC circuits. Standard outputs make the VTU-DIN reliable and easy to use with existing controllers, data loggers and SCADA equipment. It is housed in a space-saving 35-mm wide, easy-to-install DIN rail mounting enclosure.
The VTU-DIN Series features zero to 5-KHz measurement for situations where the power supplied is non-sinusoidal (such as VFD applications), poor quality installations or other electrically harsh or challenging environments. It effectively detects a wide range of conditions that may cause damage to the motor and/or soft starter components (SCRs), including: below normal/brown-out, phase loss and over voltage conditions.

New VTU Voltage Transducer from NK Technologies Measures Circuit Voltages to 1200 Volts with Single Sensor
SAN JOSE, CA – NK Technologies introduces the VTU Voltage Transducer, which can measure AC or DC circuit voltages to 1200 volts with a single sensor. The sensor produces an analog signal directly proportional to the RMS voltage, making it an ideal tool for detecting power generation issues – such brown outs and phase loss – from both conventional and alternative sources. With industry standard output options (4-20mA, 0-5 and 0-10 VDC), the VTU Voltage Transducer is compatible with most automation and control systems.
NK Technologies’ VTU Series of voltage transducers provide high accuracy and safety in a panel or DIN rail mounted housing. The VTU Voltage Transducer is used to measure voltage in a variety of applications, including pumps and aerators for water delivery and treatment systems, allowing them to be shut down quickly if the supplied voltage falls to a dangerous level. The unit can also monitor voltage of field windings in the DC motors of cranes and heavy-lifting equipment, among many other applications.

NK Technologies Introduces AGLD Fault Sensors: Large LED Display Allows Clear Viewing of Trip Point in Any Light Condition
SAN JOSE, CA – NK Technologies now offers the AGLD Series Ground Fault Sensors to keep machinery and operators safe from accidental shocks. The AGLD’s one-piece, solid-core design allows for installation over wires feeding heavy loads. The output relay will change state at any point between 5 and 100mA or 80 and 950mA. A delay can be set to allow downstream protection to activate before the sensor, keeping the main circuit protection hot and equipment energized while smaller faults are cleared. The large LED display shows the precise trip point and extra delay clearly in any light condition. Applications for the AGLD Series include monitoring of large machines, moisture ingress detection in water delivery and treatment systems, and safety in heating processes.
Key features and benefits of the AGLD Series include:
- Electromechanical relay output provides both normally open and normally closed contacts
- Compatible with most automation and control systems
- Externally powered with a choice of fail safe or standard operation
- Single-turn potentiometer with the setpoint shown on the display for easy adjustment in the field
- Solid-core case with large sensing window provides ample space for multiple conductors
- Simple DIN rail mount for quick installation

New Easy-to-Install AT/ATR-MS Series Current Transducer From NK Technologies Accurately Monitors Loads Up to 800 Amps
SAN JOSE, CA – NK Technologies introduces the AT/ATR-MS Series AC Current Transducer, combining 
a current sensing element and signal conditioner into a single package. The large, easy-to-install, split-core design allows for installation over existing conductors without the need to disconnect the load, even in applications with multiple conductors per phase. Whether installing over existing conductors or in a new control system, installation is very simple and quick.
AT/ATR-MS Series AC Current Transducer features include:
- Industry Standard Output: 4-20 mA signal proportional to the AC current, compatible with most automation systems
- Loop Powered: Use the “live zero” output to verify proper connections where the sensor output is 4 mA with no current through the sensing ring
- Split-core Case: Sensing window provides ample space for bus bar, single or multiple conductors
- Factory Calibrated: Eliminates zero and span potentiometer adjustment
- Meets UL, CUL and CE Approval
The MS Series is ideal for applications such as: monitoring large machines (measures current use to detect over/under current conditions before breakdowns occur); water delivery and treatment (detects open discharge lines and locates clogged filters and blocked intake to pumps); and grinding/shredding (allow for brief periods of drive overload when the processed product varies in density – if the blades hit something foreign the control will alarm or shut down the process.)

New DC Current Transducer Remains Accurate Across Wider Range of Changing Temperatures
Greater simplicity and usability across PLC’s, DAQ’s and power management systems
SAN JOSE, CA – NK Technologies introduces the DT Series DC Current Transducer with ambient 
temperature compensation for increased usability and accuracy. The DT Series improved accuracy is due to a new patent-pending, microprocessor-based method of signal conditioning – sensor output is automatically adjusted as temperature changes (e.g. installers do not need to add algorithms to adjust output as ambient temperature varies), eliminating one of the primary issues with Hall Elements-based products. The added signal conditioning can also eliminate the need to heat/cool the control equipment encloser, reducing considerable expense.
The DT Series DC Current Transducer is ideal for applications such as measuring photovoltaic output in panels producing less than 50 amps or less than 100 amps, as well as monitoring smaller DC motors (used in conveyors and other material positioning equipment) and electrical heaters. Key features include:
- Temperature range: -20°C to +50°C
- 333mVDC, 5 or 10 VDC output proportional to DC current
- 5 VDC or 12 VDC powered
- Monitors circuits of 600 V or lower
- Housed in split-core package so existing wiring remains undisturbed
- “Finger-safe” power supply and output terminals
- Simple two-screw panel mount or DIN-rail brackets
- Safety standards: Designed to UL508,CE standards
NK Technolgies has filed for a patent on the DT Series circuit design, and plans to offer the temperature compensation feature in its other DC current transducers in the future.
