Switched Mode Power Supplies Open Loop Hall Effect Current Sensor
TKC-H series is a kind of dismountable current sensor, which is a 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,AC or pulsed currents.
Open-loop current sensors measure AC and DC currents and provide electrical isolation between the circuit being measured and the output of the sensor (the primary current is measured without electrical contact with the primary circuit, providing galvanic isolation).

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)
The output amplitude of the sensor can be adjusted according to users’ requirements.
Custom design in the different rated input current and the output voltage are available.
