NOTES:
1. These current sense transformers have a 1 turn primary winding, secondary
turns (Ns) as indicated in the table, and a 130擄C insulation system.
2. The reference values are for unipolar operation, 50 kHz, 40% duty factor, and
an estimated 55擄C temperature rise.
3. The maximum useable peak sense current (I
PK
) depends on temperature rise
or core saturation, which should be evaluated for the operating conditions.
4. These Current Sense Transformers are recommended for switch mode power
supply applications, unipolar or bipolar, operating at frequencies from
10 kHz to 200 kHz.
5. The maximum recommended operating flux density (B
OP
) is 2000 gauss to pre-
vent saturation at an operating temperature of 105擄C.
6. The core loss factor (K
CL
) is valid from 10 kHz to 200 kHz at 105擄C.
7. The terminating resistor (R
T
) may be varied to adjust operating flux (B
OP
), droop,
or scale factor (K
VI
).
8. The scale factor (K
VI
) is proportional to the terminating resistor (R
T
) and is equal
to 1 volt/amp when R
T
=N
S
.
9. The secondary inductance (L
S
) is measured at 15 kHz and .5V for PE-67050,
1V for PE-67100, 2V for PE-67200 and 3V for PE-67300.
