Title: Inductance readings for PT-10 and PT-11
Post by: mravunko on October 01, 2022, 02:42:25 AM

Hi,

I would like to make a LTSpice schematic of my Crack and Reduction BUT the software simulates a transformer as two (or more) coupled inductors. Furthermore my transformers are already soldered and I have to de-solder at least the secondaries in order to measure the inductance. So I kindly ask if somebody already has this data to share it with me. If you have it for 230V will be the perfect  ::)

Thanks.

Here's some info on getting that info entered:

Thank you!
I got it. Just assume that primary winding has 1H inductance and calculate the ratios for the other.
