Accurately measure sinusoidal, distorted, or pulsed current wave shapes without additional hardware and its associated costs and space requirements
NK Technologies introduces the ATH Series AC Current Transducer. The ATH is specifically designed to monitor power controlled by phase-angled fired, burst fired or time proportioned silicon-controlled rectifiers (SCRs) in heating applications, without requiring an external current transformer or shorting blocks. Patent pending Time Integration functionality incorporated in the ATH design provides an output signal directly proportional to the RMS amperage to ensure accuracy regardless of the AC current wave shape. The sensor samples the AC current continuously, updating its own time base when the current returns to the load after a pause. Based on the magnitude of the burst and the time interval between bursts, the sensor output represents the amount of power used by the connected load.
WRT operates transparently with existing equipment, wirelessly transmits data over long distances, and requires no changes or cabling to add devices to existing networks
NK Technologies introduces the WRT Series Wireless Data Transmitter/Receiver. This wired-to-wireless solution provides a self-managed mesh network that works with any RS485 network protocol to promote highly reliable system operation in new or retrofit applications. The system allows for wired and wireless equipment mixes to avoid radio signal obstacles. It is also simple to configure for existing network packet parameters, provides LED indication of network status and is completely transparent to present equipment. WRT users will benefit from wireless data transmission of up to 100 meters between receivers, and data transmissions up to 800 meter transmissions are possible with multiple hops.
ATS receives Silver award in the electrical controls category
The ATS Current Sensing Switch and Transducer from NK Technologies has received the Silver award for Electrical Controls in the 2012 Plant Engineering magazine Product of the Year contest. The ATS series is a compact one piece solution that combines a limit alarm with an analog output signal transducer to monitor produced or consumed AC current up to 1200 amps, while magnetically isolating outputs and inputs to maximize safety. An innovative and patent pending rotary switch makes it easy for users to set the trip point. DIN rail mounting simplifies installation and provides an extremely secure mount that is resistant to conductor movement.
“E-Out” AC current transducers combine a transformer and true RMS signal conditioner in a single package
NK Technologies introduces ATPR “E-Out” Series AC Current Transducers. ATPR current transducers combine a current transformer with a true RMS signal conditioner in a single package. This enables the ATPR series to produce a 0-5 or 0-10VDC RMS output on distorted waveforms located in the output of variable frequency drives, phase angle fired heating controls, and on linear loads in “noisy” power environments.
NK Technologies introduces DS1 DC Current Sensors. DS1 current sensors feature a compact and non-adjustable one-piece design to deliver reliable detection of very low DC current levels in a wide range of applications. Their compact and non-adjustable one-piece design simplifies installation, even in crowded control cabinets. DS1 current sensors can be powered by any DC voltage between 10- 28 volts and use the same circuit as the one being controlled, or a separate source of voltage to power the sensor as long as the circuit being controlled uses the same ground. This further simplifies installation and operation when compared with other current sensors.
NK Technologies introduces ASL Series AC Current Operated Switches. The ASL series features a patent pending and user-selectable linear setpoint adjustment, enabling users to reliably monitor current, simply, in a wide range of applications. The ASL series is available in a panel mounted solid- or split-core enclosure to simplify installation. An easily established contact actuation point can be set with no load present and a two second delay ignores motor inrush current upon energization. Magnetically isolated output maximizes safety and eliminates insertion losses, and solid-state reliability eliminates periodic maintenance or calibration requirements. No external power source is required for operation.
NK Technologies introduces ADC Series Analog to Digital Signal Converters. The ADC series readily accepts analog signals from up to eight loop or separately powered current, voltage, temperature or any other parameter sensor, and seamlessly converts them to a digital signal output that interfaces with the industry standard Modbus RTU digital protocol using a single network address. DIN rail mounting speeds installation. Sensor loop power supplied by the converter can eliminate the needs for a separate DC power supply. The ADC series can be factory-set for 120 or 240VAC power supplies.
Current relay provides control engineers with features that help solve maintenance requirements for single and three-phase motors
NK Technologies’ ASXP Current Sensing Switch is now available with a user-adjustable setpoint from 1-80A. ASXP Series Current Operated Switches are powered versions of the company’s popular current switches with integral time delay. For use with 24 VAC/DC or 120 VAC supplies, these switches deliver OEM-caliber accuracy, precision tolerances, low hysteresis and an operation range between 40 and 100 hertz – functionality ideal for monitoring single and three-phase motors. They come standard with a robust solid-core enclosure and LED indicators for trip point contact status.
ATS monitors AC current up to 1200 amps and provides complete isolation between the primary circuit and controls in a single, compact package
NK Technologies introduces the ATS Current Sensing Switch and Transducer. The ATS series is a one piece solution that combines a limit alarm with an analog output signal transducer to monitor produced or consumed AC current up to 1200 amps, while magnetically isolating outputs and inputs to maximize safety. An innovative and patent pending rotary switch makes it easy for users to set the trip point.

New self-calibrating and self-powered Smart-Switch eliminates the need to manually adjust the sensor trip point, and is compatible with any automation system
NK Technologies introduces the newly re-designed ASM Series Smart-Switch. These self-calibrating switches use the actual load current to set the trip point and provide the simplest way to ensure that a motor is working properly. These current sensing Smart-Switches are self-powered and self-calibrating to speed start-up and minimize installation costs. Three models are available to provide status monitoring, overload or under load, or operating window (overload and under load) functionality to suit particular pump, fan, heating element, conveyor or multi-load safety-interlocked application needs. The output contact is AC and DC compatible for use with any automation system.
