ATS Series (digital display) by NK Technologies

Product Description
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.
  • Electronic Proof of Operation
    • Current operated switches eliminate the need for multiple pipe or duct penetrations and are more reliable than electromechanical pressure or flow switches.
  • Conveyors
    • Detects jams and overloads
    • Interlocks multiple conveyor sections.
  • Pump Control
    • Provides Signal to measure current and shuts down the pump if the current rises over a setpoint.
  • Cooling Towers
    • Analog monitors time of use and contact opens if a filter clogs.


Solid-State Output

  • N.O. or N.C. solid-state switch for control circuits up to 240 VAC.
  • compatible with most automation systems.

Externally Powered

  • Allows for higher accuracy.

Easily Adjustable and Precise Setpoint

  • Speeds startup.

Analog Output

  • Measure the current used at all times.

LED Display

  • Provides quick visual indication of where the contact changes. Display flashes on and off when current has exceeded the setpoint.
  • Easiest and most accurate setpoint adjustment available.

Built-in Mounting Feet

  • Simple, two-screw panel mounting or attach with DIN rail brackets (included)

Designed for UL/cUL and CE Approval

  • Accepted worldwide.
