Current Sense Transformers
Description:
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 over the frequency range of
20 kHz-200 kHz.

Technical Notes:
1. Derate ET product by 32% for 50 kHz, 52% for 100 kHz and 50% for
unidirectional operation.
2. Rated primary current renders approximately 40°C temp. rise.
3. Maximum recommended terminating resistance of 1 ohm per turn.
4. Primary is inserted through hole in casting.
