NK Technologies

  NK Technologies has released the 2019 product catalogue, 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. 

The DG series DG Ground fault detector has been introduced as the latest innovation from NK Technologies. The DG series was designed to keep operators and machinery safe from accidental shocks by detecting fault currents quickly and easily, and can be installed at a fraction of the cost of products currently available.

  Being able to measure AC or DC circuit voltages up to 1,200V with a single sensor is now possible with the new the VTU Voltage Transducer from NK Technologies.

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.

NK Technologies has a new addition to its line of 5A Secondary Current Transformers. The CT-MS has a split-core design and larger than average sensing window, making it ideal for installing over large wires or bus bars. The CT-MS measures AC current and produces a 0 – 5 amp output proportional to the current flowing through the sensing window. 

NK Technologies offers a wide range of ground fault indicators, including the AGT Series. The AGT Series produces an analog 4–20 mA signal proportional to earth or ground fault current. When connected to a controller or data logger, NEC requirements for alarm can be met. Applications include current leakage detection (monitors heating or other loads to detect increases in leakage current) and accurate measurement of very light loads (providing faster response than temperature measurement).  

NK Technologies’ externally powered APT Series Power Transducers are now available with 24VAC/DC, 120VAC or 240VAC power supply options to support a wider range of applications. These transducers produce an industry standard 4-20 mA, 0-5 VDC or 0-10 VDC output that can help users monitor and report power usage, enabling them to take proactive corrective action when power rises to abnormal levels or falls to unexpected levels. The APT power transducer can be configured to accept 5 amp secondary current transformers, or NK Technologies’ ProteCT low voltage output sensors. Either type of current sensing will produce an accurate output signal to help identify areas of excessive energy consumption and allow intervention to reduce demand.

NK Technologies solid-core case ATH Series Current Transducers with Time Integration now accommodate 120 VAC power supplies for use in heater monitoring applications. ATH current transducers are also available in solid-core or split-core 24 volt models. ATH current transducers are compatible with most automation systems and are ideal for monitoring burst fired time proportional control of heating systems. The ATH series also feature a simple two-screw panel mount and optional DIN rail brackets for quick and easy installation.

A series of current sensing switches, providing a limit alarm contact, has been introduced by NK Technologies. The company claim that the ASD Series provide the alarm contact with the easiest adjustment method ever designed. Featuring a single turn potentiometer, the switches allow the trip point to be set before the sensor is installed or before the monitored circuit is energised.

The AT/ATR-LS Current Transducer, available from NK Technologies, combines a current transformer and signal conditioner to monitor large loads. The AT/ATR-LS is easy to install due to a large, split-core design that can be installed over existing conductors without disconnecting the load, even in applications with multiple conductors per phase.
