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, where the sensor output is 4 mA with no current through the sensing ring.
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:
- Simply snaps onto DIN rail for secure mounting.
Designed to Meet 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.
- Locate clogged filters or blocked intake to pumps.
Grinding and Shredding:
- An analog output will allow the control system designer to allow brief periods of drive overload when the processed product varies in density. If the blades hit something foreign (e.g. steel when the machine is designed to reduce paper), then the control will alarm or shut down the process.

Description

AT/ATR-MS Series AC Current Transducer

AT/ATR-MS Series Current Transducers combine a current sensing element 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. Whether installing over existing conductors or in a new control system, installation is very simple and quick. 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 or the load, (a programmable logic controller, a panel meter, or a data acquisition system).
