ATS Series with Digital Display Setpoint



ATS Series AC Current Sensors combine a current operated switch and transducer into a single package. The FL model features a digital display that gives visual indication of the setpoint for greater accuracy. The sensor provides a solid- state contact which will change state when the current exceeds an adjustable level or falls below the normal running current. This means reduced installation time, plus the option to have local control of a starter coil while at the same time sending the analog signal back to a controller housed in a separate cabinet.

ATS AC Current Transducer

The ATS AC Current Transducer/Switch. Monitoring High Current Loads Easy and Safe.

The new ATS Series is specifically designed to protect loads with current levels up to 1200A. This patent pending, one-piece solution combines a limit alarm (switch) with an analog output signal transducer. The large sensing window provides complete isolation between the primary circuit and the controls. The ATS eliminates the need to use a screwdriver inside an energized control panel to manually adjust the sensor. Helps with NFPA70E compliance.


  • Patented rotary switch setpoint selection (patent pending).
  • Output is magnetically isolated from the input for safety.
  • Analog signal powered from the sensor; no loop powered required.
  • 4-20mA signal proportional to 0-1200 AC Amps.
  • Single Pole Double Throw Relay changes state with power to sensor.
  • LED indication if power is removed from the sensor or primary current exceeds adjustable trip point.
  • Integral DIN rail mount with spring loaded mounting clips.


The ATS eliminates the need to connect multiple components to monitor high current loads. It can be used to directly monitor AC motor loads to 500 horsepower.

Monitor air handling blowers, pumps, crushers and many other large loads with one self-contained current switch (limit alarm) while also using the built in analog signal to spot bearing wear and other issues before they cause a break down. As a tool in your preventive maintenance tool kit, the ATS is incomparable.
