"APN" & "APO" Power Transducers from NK Technologies feature the patented Autophase technology which helps to correct common wiring errors ranging from CT reversal to phase mismatch. Analog 4-20mA or 0-5/10VDC (proportional to kW) and pulse kWH outputs are available as standard options in either standard Modbus or RS232 Configurations.

Applications

• Cost Allocation - Measures and displays power, both Demand (KW) and consumption (KWH).
• Improve Plant Performance
• Machine Control - KW monitoring provides a good picture of machine tool operation.
• Generator Performance - Provides a cost effective way to monitor power output from back up generators, ensuring "Information Age" standards.

The 'VTR' Series from NK Technologies is a high-performance True RMS voltage 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.

Features

• Accurate, True RMS Voltage Measurement
• Slim, DIN-compatible 23mm Wide Enclosure
• Fast Response for Precise Control and Monitoring
• 24 V Loop-Powered; Std. 4-20mA Proportional Output
• CE Approved, UL Recognition Pending

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.
