These current sense transformers have two one turn primaries that can be 5. The temperature rise of the component is calculated based on the total core loss used in parallel. The listed current ratings are for parallel connection. and copper loss: 2 2. The reference values are for an application using the termination resistor A. To calculate total copper loss (W): P(cu) = Ipk * Req * Ff * don where Ff is 1 for (Rt) and operating with unipolar waveform at 100kHz, 40% duty cycle. unipolar waveform and 2 for bipolar waveform 1.67 The estimated temperature rise is 55C. B. To calculate total core loss (W): P (core) = 0.000073 * (Freq. in kHz) * (Bop in 2.532 3. The peak flux density should remain below 2100 Gauss to ensure that the kG) where: Bop in kG = Kb * Ipk * Rt * don/(2000 * Freq. in kHz) core does not saturate. Use the following formula to calculate the peak C. To calculate temperature rise: Temperature Rise (C) = 60.18 * (Core Loss (W) + .833 flux density: Bpk = Kb * Ipk * Rt * don/(Ff * freq. in kHz) where: Rt is the Copper Loss (W)) terminating resistor in the application and the Ff is 1 for unipolar waveform and 2 for bipolar waveform. 4. To calculate the droop: Droop Exponent (D) = Rt * don/(Lpri in mH * Freq. in kHz -D %Droop = (1-e ) * 100 1 power.pulseelectronics.com P516.D (02/19) THT Current Sense Transformers P0581NL / P0582NL AND P0583NL Mechanical Schematic P058XNL .810 .580 MAX MAX 20,57 14,73 .750 MAX 19,05 P058X Date Code Country of Origin .130 3,30 .700 17,78 3 Weight ..................................................5 grams 10 7 1 4 Tray ........................................................80/tray .Inches .350 Dimensions: mm (6X) .040 8,89 Unless otherwise specified, ..010 all tolerances are: 0,25 7 10 14 .200 8 5,08 SUGGESTED PCB HOLE PATTERN For More Information Pulse Worldwide Headquarters Pulse Europe Pulse China Headquarters Pulse North China Pulse South Asia Pulse North Asia 15255 Innovation Drive Ste 100 Pulse Electronics GmbH Pulse Electronics (ShenZhen) CO., LTD 3 Fraser Street 0428 1F., No.111 Xiyuan Road Room 2704/2705 San Diego, CA 92128 Am Rottland 12 D708, Shenzhen Academy of DUO Tower Zhongli District Super Ocean Finance Ctr.
