K11TP Type Current Sensor


K11TPseries dismountable hall effect current Sensor is an open 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 DC currents.

Directions for use:

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


  • AC variable speed drives
  • Static converters for DC motor drives
  • Variable speed drives
  • Power supplies for welding applications
  • Battery supplied applications
  • Uninterruptible Power Supplies (UPS)
  • Switched Mode Power Supplies (SMPS)
