#100 No-Name-Netzteil auf dem Prüfstand – Was steckt wirklich drin?

I'm taking a close look at a 12V plug-in power supply that has a type designation but lacks a correct CE marking, test mark, or manufacturer's name. I'm testing its performance, insulation, ripple, overload, and short circuit, and examining its internal components in detail. Is such a power supply safe to use in everyday life – or is it more of a safety risk? 0:00 Intro 6:52 Insulation test 9:56 Power plug 11:37 Mains voltage test 12:09 Load test 12:45 Ripple 14:45 Overload 16:18 Short circuit test 19:11 Disassembled 23:35 Main IC 26:49 Transformer 30:32 Conclusion 31:31 Outro Twitter:   / elektroniklabor   LBRY: https://lbry.tv/@ElektronikLabor
