AT / ATR-LS Series AC Current Transducers – NK Technologies


800-1600A AC Current Transducers with Split Core Case
AT/ATR-LS Series Current Transducers combine a current transformer and signal conditioner into a single package. The large, easy-to-install split-core design allows for installation over existing conductors without the need to disconnect the load, even in applications where there are multiple conductors per phase. For new installations, the installation is just as easy. Just remove the top portion of the sensing ring, place the conductors inside, and snap the top back in place. The transducer uses two wires to connect to the power supply and the load, programmable logic controller, panel meter or data acquisition system
