These current sense transformers have a 1 turn primary winding, secondary turns (Ns) as indicated in the table, and a 130°C insulation system. 2. The reference values are for unipolar operation, 50kHz, 40% duty factor, and an estimated 55°C temperature rise. 3. The maximum useable peak sense current (IPK) depends on the 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 10kHz to 200kHz. 5. The maximum recommended operating flux density (BOP) is 2000 gauss to prevent saturation at an operating temperature of 105°C. 20 80 180 1.40 4.50 11.0 200 300 .00746 x 10 0 4 4 6.13 x 10 6. The core loss factor (KCL) is valid from 10kHz to 200kHz at 105°C. 7. The terminating resistor (RT) may be varied to adjust operating flux (BOP), droop, or scale factor (KVI). 8. The scale factor (KVI) is proportional to the terminating resistor (RT) and is equal to 1 volt/amp when RT=NS. 9. The secondary inductance (LS) is measured at 15kHz and .5V for PE-67050, 1V for PE-67100, 2V for PE-67200 and 3V for PE-67300.
