'AT' Current Transducers from NK Technologies combine a current transformer and signal conditioner into a single package. The AT Series has jumper selected current input ranges and industry standard 4-20mA, 0-5VDC or 0-10VDC outputs. The AT Series is designed for application on 'linear' or sinusoidal AC loads. Available in a split-core case or two types of solid-core cases.
