Excellent quality transformers that are completely silent. Way better than the green BingZi types that are popular in ChiFi devices. Do you have types with other voltages?
Hi JP. Unfortunately not no. I do like them. Makes for a tidy and compact build. I'm just trying to learn kicad to do my own PCB with 3 of these on.
Yes, one of the rare real quality devices one can still* find. I design PSUs with them. One point of attention is not to use them at the outer power limits as their heat exchange with the environment is of course less good than that of open types.
Some tips: since they are broadband always use mains filtering at the primary side. At the secondary side it pays off to do CLC filtering. They are not only good in 50 Hz so to speak and this goes both ways.
*There was some electro gossip over there telling that some manufacturers will stop producing transformers because of worldwide demands with regards to required power efficiency.

I’ve made a small PCB for something similar and added some fuses on the primary and secondary sides. I used EasyEDA
I'm personally out of these but have asked where they came from if there's any left over. Shall reply back and sorry to @Frabor for my lack of reply.
