NOTES:

1. These current sense transformers have a 1 turn primary winding, secondary

turns (Ns) as indicated in the table, and a 130°C insulation system.

5. The maximum recommended operating flux density (BOP) is 2000 gauss to pre-

vent saturation at an operating temperature of 105°C.

2. The reference values are for unipolar operation, 50 kHz, 40% duty factor, and

an estimated 55°C temperature rise.

6. The core loss factor (K^CL) is valid from 10 kHz to 200 kHz at 105°C.

7. The terminating resistor (R^T) may be varied to adjust operating flux (BOP), droop,

or scale factor (K^VI).

3. The maximum useable peak sense current (I^PK) depends on temperature rise

or core saturation, which should be evaluated for the operating conditions.

8. The scale factor (K^VI) is proportional to the terminating resistor (R^T) and is equal

to 1 volt/amp when R^T=NS.

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.

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.
