But as for the insulation, is there anything I can specifically ask for, from the person winding the transformer? Or check with a multimeter? or check if it burns in a flame? | |
| Apr 12, 2018 at 12:16 | comment | added | Indraneel | The equivalent in India is the ISI Mark en.wikipedia.org/wiki/ISI_mark . But it may be difficult to get hold of such a transformer, as they are usually marked only for manufacturers buying in bulk. It is easier to get a custom wound transformer. But, I have no idea what to ask for regarding insulation. As for SMPS, that are all imported from..... and who knows about the authenticity of the CE mark on it. | |
