NK Technologies True RMS ac or dc voltage transducer
The VTU-DIN series is a true RMS transducer for sensing voltage in single, three-phase or dc installations. The transducer measures 0-15 to 0-600 V with an industry-standard output proportional to connected voltage in ac circuits with sinusoidal or non-sinusoidal (variable-frequency) applications or dc circuits. Standard outputs make the transducer easy to use with existing controllers, data loggers and SCADA equipment. It is housed in a space-saving 35-mm-wide DIN rail mounting enclosure. The series features 0- to 5-KHz measurement for situations in which the power supplied is non-sinusoidal (such as VFD applications), for poor quality installations or for other electrically harsh or challenging environments.
