dual secondaries transformer only using one
Thanks FvM ! Transformer is marked 067.039. So, it's the same,I've ordered. You are right about the overview catalogs. In one of them this transformer was noted to be a single secondary 27-30V/3,2A,in other - a double secondary 27-30V. I've examined several overview catalogs,from different years and places and all of them state that secondary is 27-30V (single or double). I can't believe that if there is a mistake,Kaschke hasn't eliminated it. This part has been on market for years.
The transformer has two secondary windings indeed. But why in the datasheet is stated ,as you say,a single one? And why 15V? And what about transformation ratios - 1:0,266:0,6:1 - aren't they too low, promting that secondary winding should be a higher voltage one,not 15V :?:
