Hi!
I have attached image to this post.
I have marked some cloth sleeves with nr 1 and some plastic cover with nr 2. Does anyone know what is the use of those and are they required? These sleeves with nr 1 are not shrinking tubes. but since they are already around insulated wires, I cant think of any practical use so I thought I would ask those smarter than me. Other thing is plastic cover on top of transformer. Would something happen if it were removed? If the metal case is grounded and some parts of transformer's outer metal frame touch the metal case, would some current flow to case?
Also one question is that the yellow part of that transformer frame is 5.5 cm from left to right. Based on size of that high frequency (likely around 100kHz) transformer (13:1 ratio) how much power would be reasonable to expect it to deliver with out forced cooling by fan? In my case 50W load got it to around 80C and 70W load got it around 100C. Is it normal for such relatively small load to generate that much heat in transformer?
