Designed for switching power supply applications, Triad current sense transformers are used to detect the current passing through a conductor.

These transformers are very reliable and operate effectively over the frequency range of 20 kHz - 200 kHz. They are constructed of UL rated 130 ºC materials. Both models are available with a center tap option.
