0-400 Amp Range, Base Terminals

0-400 Amp Range
Industry Standard Output:
- 4–20 mA signal proportional to the AC current
- Compatible with most automation 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 Approval:
- Accepted around the world

AC Current Transducer Applications

Monitor Large Machines:
- Measure the current use to detect over or under current conditions before they cause break downs.
Water Delivery and Treatment:
- Detect open discharge lines.
- See clogged filters or blocked intake to pumps.
Generators:
- Keep the power system running by monitoring the output.

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.
