NK Technologies VTR Series True RMS Voltage Transducers Distributors
Voltage Transducers

The 'VTR' Series from NK Technologies is a high-performance True RMS transducer for single- and three-phase sensing. Applicable on nominal circuits of 120V, 240V and 480V, the VTR provides a fully isolated 4-20mA output proportional to percent of nominal voltage, even in situations with non-sinusoidal waveforms. A compact enclosure, DIN-Rail compatibility and snap-fit quick-connect terminal blocks make installation and wiring quick and easy.

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 enclosure, the VTD Series comes in a variety of nominal voltages.

NK Technologies CTC Series Signal Converters 5 Amp Secondary & .333mVAC Distributors

Signal Converters

Signal Converters

CTC Series Signal Converters allow you to use an existing standard 5 amp secondary or low-voltage ProteCT current transformer over a conductor to produce an industry standard 4-20 mA 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.

The ADC Series connects up to eight 4-20 mA looppowered analog sensors, or up to eight separately powered 4-20 mA output sensors, or up to four of each. This will produce a digital signal representing 0-100% of each sensor output. It is the perfect solution for photovoltaic power production system monitoring. The ADC converter allows for individually-ranged devices to interface with the industry standard Modbus RTU serial protocol.

NK Technologies' Parent Company was a System Integrator. Neilsen Kuljian began automating industrial sites in Silicon Valley in 1982. An early NK Technologies project required close control of AC motors and electric resistance heaters. A thorough search found that there were no products available that could accurately monitor these loads. So NK Technologies engineers developed a unique self-contained current operated switch. Word of this NK Technologies Current Switches invention quickly spread throughout the control engineering community. Orders began coming in from System Integrators and NK Technology distributors across the country and around the world.

In 1986 the Board of Directors decided that Neilsen Kuljian should focus on developing innovative, current sensors and power monitoring products. This decision led to tremendous growth, which, in turn, led to a flood of new products Current Transformers, Current Switches, Current Transducers, Ground Fault Sensors, Power Monitors, Voltage Transformers, and Voltage Transducers. In the late 1990's, the NK Technologies division was formed to meet the overwhelming demand for new products and services from Industrial Integrators, distributors and End users. A network of Neilsen Kuljian Manufactures Representatives and Authorized NK Technologies distributor brings technical expertise and quick product delivery around the world.

Neilsen Kuljian ATR transducers use a mathematical algorithm called "True RMS," which integrates the actual waveform over time. Select Neilsen Kuljian ATR transducers for nonlinear loads or in "noisy" power environments. ATR transducers from NK Technologies combine a current transformer and a True RMS signal conditioner into a single package. NK ATR Current Transducers are available in a solid or split core case. AT Current Transducers from NK Technologies combine a current transformer and signal conditioner into a single package. The AT Series NK Current Transducer has jumper selected current input ranges and industry standard 4 to 20mA, 0 to 5VDC or 0 to 10VDC outputs. AT/ATR 3 and 4 transducers from NK Technologies combine a high capacity current transformer and a signal conditioner into a single package. The ATR version of NK Technology Current Transducer is True RMS for use on distorted waveforms found in VFD or SCR outputs. DT Current Transducers from NK Technologies combine a Hall effect sensor and signal conditioner into a single package. The DT Series Current Transducer has jumper selectable current input ranges and industry standard 0-20mA, 4-20mA, 0-3VDC, 0-5VDC or 0-10VDC outputs.
