through hole current sense transformers vde approved meets iec950 insulation requirements 3750v rms primary to secondary breakdown voltage frequency range 10khz to 200khz electrical specifications @ 25c ? operating temperature -40c to 130c notes: 1. these current sense transformers have a 1 turn primary winding, secondary turns (ns) as indicated in the table, and a 130c insulation system. 2. the reference values are for unipolar operation, 50khz, 40% duty factor, and an estimated 55c 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 10khz to 200khz. 5. the maximum recommended operating flux density (b op ) is 2000 gauss to prevent saturation at an operating temperature of 105c. 6. the core loss factor (k cl ) is valid from 10khz to 200khz at 105c. 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 15khz and .5v for PE-67050, 1v for pe-67100, 2v for pe-67200 and 3v for pe-67300. 10. to order rohs compliant part, add the suffix ? nl ? to the part number (i.e. PE-67050 becomes PE-67050 nl ).
