Aug. 19, 2014 – NK Technologies’ AT/ATR-LS Current Transducer combines a current transformer and signal conditioner for monitoring large loads. The AT/ATR-LS is easy to install due to a large, split-core design that can be installed over existing conductors without disconnecting the load, even in applications with multiple conductors per phase, the company says. It measures current use to detect over or under current conditions. Features include industry standard output, loop-power, factory calibration, a split-core case and DIN rail mount. The transducer uses two wires to connect to the power supply and the load: programmable logic controller, panel meter or data acquisition system.
