A-N1T Type Current Sensor


A-N1T series hall effect current Transmitter is an Closed loop device based on the measuring principle of the hall effect, 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 transmitter, the voltage will be measured at the output end. (Note: The false wiring may result in the damage of the transmitter)
  • Customs can adjust output amplitude of the transmitter by needs.
  • 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
