Hall effect current sensor A-C2 Type

Hall effect current sensor of A-C2 series is a detachable Hall effect current transducer, Hall effect current sensor is an open-loop device based on the Hall effect measurement principle., with a galvanic isolation between primary and secondary circuit. It provides accurate electronic measurement of AC or pulsed currents.

Directions for use:

  • When the current will be measured goes through a sensor, the current will be measured at the output end. (Note: The false wiring may result in the damage of the sensor)
  • Custom design in the different rated input current and the output voltage are available.


  • Variable speed drives
  • Welding machine
  • Battery supplied applications
  • Uninterruptible Power Supplies (UPS).
  • Electrochemical
