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.

INDUSTRY STANDARD  OUTPUT

• 4–20 mA signal proportional to the AC current
• Compatible with most automation and control systems

LOOP-POWERED

• Use the “live zero” output to verify proper connections (sensor output with no current flowing confirms the system is ready to go)

FACTORY CALIBRATED

• Eliminates zero and span potentiometer adjustment

SPLIT-CORE CASE

• Sensing window provides ample space for bus bar, single or multiple conductors

DIN RAIL MOUNT

• Simple snap onto DIN rail for secure mounting

DESIGNED FOR UL, CUL AND CE APPROVED

• Accepted worldwide
