Seamlessly Convert a CT Signal to a Standard 4-20mA Output

Provides simple solution for monitoring current in applications where one-piece sensors are impractical or impossible to install
NK Technologies introduces CTC Series Signal Converters. With the CTC series users can utilize an existing standard 5 amp secondary CT or low voltage (0.333 VAC) ProteCTTM current transformer with non-contact ranges as low as 0-5 amps over a conductor to produce a standard 4-20mA two-wire, loop-powered signal. With DIN rail mounting and a 24 VDC loop-powered supply, the CTC series provides simple snap-in installation that requires no calibration because the primary current transformer ratio provides the scaling required without any installer intervention.

Easily Monitor DC Current with New DT Series Current Transducers

Large aperture design makes it easy to seamlessly monitor any circuit up to 1200 amps
NK Technologies introduces DT Series Large Aperture Current Transducers. The DT series combines a hall effect sensor and signal conditioner into a single package for use in DC current applications up to 1200 amps. Factory calibrated ranges simplify operation and eliminate zero and span pots. Industry standard 4-20mA, 0-5VDC or 0-10VDC outputs are magnetically isolated from the input to provide maximum safety, and eliminate insertion losses. Internal power regulation delivers reliable operation and helps keep installation costs low, even in applications with unregulated power. A DIN-rail mount enclosure makes installation easy..

Easily Monitor Current Usage of Loads up to 2000 Amps with ATCR

Innovative design enables installer to pass the coil around the conductors, without having to disconnect existing wires.  NK Technologies introduces ATCR Series Current Transducers. ATCR flexible loop current transducers are a perfectly matched and factory calibrated sensing coil and True RMS signal conditioner that use just two wires to provide the power supply and output signal, while eliminating the need to disconnect existing wires. This makes them a uniquely simple and convenient means of monitoring resistive or inductive loads to detect current usage on large machines using AC current up to 2000 amps. They meet UL508 and CE requirements, making them suitable for global application.

Maximize Motor and Drive Operating Life Prevent System Failures with new VTD High Performance Voltage Transducer

VTD series is a cost-effective solution for monitoring, detecting and diagnosing voltage conditions in DC powered installations NK Technologies introduces VTD Series high-performance voltage transducers. Packaged in a compact and easy-to-install 35mm wide DIN-rail enclosure, the VTD series senses voltage in a wide variety of DC powered installations, including industrial motors, battery chargers, photovoltaic arrays and wind generators. These cost-effective voltage transducers help avoid motor overheating by detecting below normal voltage conditions, and detect voltage conditions that can stress or damage starter components. Monitoring DC voltage enables operators to know that the system is ready even before there is a load connected to it.

New CTC Series Signal Converter

CTC Series Signal Converters allow you to use an existing standard 5A secondary or low-voltage ProteCT™ current transformer over a conductor to produce an industry standard 4-20mA two-wire, loop-powered signal. The signal is proportional to the current in the primary circuit. The CTC series snaps onto a standard DIN rail. The output is connected to the load and a 24 VDC source and the current transformer is connected.

New VTD Series DC Voltage Transducers

VTD Series Voltage Transducers are high-performance transducers for sensing voltage in DC powered installations. Applicable for use on circuits to 600 VDC, VTD voltage transducers provide a fully isolated, 4-20mA output proportional to rated nominal voltage in DC circuits. Housed in a slim, compact, easy-to-install DIN rail mount case, the VTD Series comes in a variety of nominal voltages.
 

New ATCR Series Flexible Cable AC Current Transducer

NK Technologies’ flexible cable current sensors wrap around the conductor using very little space. The cable is connected to a signal conditioner located up to several feet away from the conductor, and produces an industry standard 4 to 20 mA signal in proportion to the AC current. With ranges of 0–500 to 0–2000 amps and frequencies to 400 hertz, the ATCR series is well suited for a wide range of applications.
