WE-CST & WE-CSTLF Current Sense Transformers

Würth Elektronik WE-CST and WE-CSTLF Current Sense Transformers utilize inductive coupling on a transformer to convert the input and output currents and voltages based on the turns ratio. The current sense transformer features a primary winding with few turns and a secondary winding with many turns. Current passing through the primary induces a current in the secondary, which can then be converted into a measurable voltage using a burden resistor as the load. Therefore, the output voltage is directly proportional to the input current, making the current sense transformer an effective tool for current measurement.
