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

ABOUT NK TECHNOLOGIES

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.)

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.

SAN JOSE, CA – NK Technologies offers a wide range of ground fault indicators, including the AGT Series Ground Fault Indicator. 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).

Key features AGT Series features include True RMS Output – remains accurate on distorted waveforms like VFD or SCR outputs; Single Range – eliminates field range selection errors and zero and span pots; and Isolation – magnetically isolates output from the input for safety and eliminates insertion loss.

AGT Ground Fault Indicator Series specifications include:

• Output Signal: 4 – 20 mA, Loop-powered, True RMS
• Output Limit: 23 mA
• Accuracy: 1,0% FS from 10% to 100% of range
• Frequency Range: 40-400 Hz
• Power Supply: 24 VDC Nominal, 12-24 VDC
• Response Time: 600 ms (to 90% step change)
• Standards: UL, CUL 508 Listed
