Compact split-core AC current sensors for energy monitoring and process automation. The split core opens and clamps around an existing cable without disconnection. Based on curent transformer technology, the AT Series integrates sensing and signal conditioning for accurate, reliable measurement with galvanic isolation between primary and secondary circuits.

The 4–20mA output variant is loop-powered require an auxiliary supply. The 0–5V and 0–10V voltage output variants, eliminating the need for a separate auxiliary supply. All models feature a 16mm aperture and a UL94-V0 rated insulating plastic case.

Applications include process regulation via distributed PLCs and SCADA, load monitoring for protection and predictive maintenance on conveyors, pumps, and HVAC motors, and AC current measurement in energy management panels.
