These current sense transformers have two one turn primaries that can be used in parallel. The listed current 4. The temperature rise of the component is calculated based on the total core loss and copper loss: ratings are for parallel connection. A. To calculate total copper loss (W): P(cu) = Ipk2 * DCR Sec * Ff * don where: Ff is 1 for unipolar waveform and 2. The reference values are for an application using the termination resistor (Rt) and operating with unipolar 2 for bipolar waveform waveform at 100kHz, 40% duty cycle. The estimated temperature rise is 55C. B. To calculate total core loss (W): P(core) = 0.000073 * (Freq. in kHz)1.67 * (Bop in kG)2.532 where: Bop in kG = 3. The peak flux density should remain below 2100 Gauss to ensure that the core does not saturate. Use the fol - Kb * Ipk * Rt * don/(2000 * Freq. in kHz) lowing formula to calculate the peak flux density: Bpk = Kb * Ipk * Rt * don/(Ff * Freq. in kHz) where: Rt is the C. To calculate temperature rise: Temperature Rise (C) = 60.18 * (Core Loss(W) + Copper Loss (W)).833 terminating resistor in the application and Ff is 1 for unipolar waveform and 2 for bipolar waveform Mechanicals Schematic PA3655NL .810 MAX 20,57 .580 .700 MAX 14,73 17,78 10 7 .350 .750 MAX (6X) .040 19,05 8,89 4 1 .200 Weight.............................5 grams 5,08 T r a y ...................... 20/ tr a y .130 SUGGESTED PCB HOLE PATTERN 3 Inches 3,30 14 Dimensions: mm .010 Unless otherwise specified, all tolerences are 10 7 0,25 8 For More Information Pulse Worldwide Pulse Europe Pulse China Headquarters Pulse North China Pulse South Asia Pulse North Asia Headquarters Zeppelinstrasse 15 B402, Shenzhen Academy of Room 2704/2705 135 Joo Seng Road 3F No. 198, Zhongyuan Road 12220 World Trade Drive 71083 Herrenberg Aerospace Technology Bldg.
