Short circuit in a Switched power supply /charger

[hafrse]

Hello,

If I measure on the copper shield of the transformer (se picture above) , after 30 min the temperature is about 50 Deg C, but I suspect it is higher when the power supply is boxed in it Alu encloser . may be that is ok, not sure. The charger charges a Nicd 12V battery at 16V 400mh according to the manual.

Now had gone about 2 hours , stablizes at 51 Deg C. In the closed aluminium encloser , there are no fans or vents...

How hot can these types for transformers will get?

I started another thread on that particular issue :

"How hot can the flyback transformer core on a 60 Watts SMPS be ?"​

Bad idea. Forum rules suggest to post similar questions in one thread.
