Just purchased two 240/48 volt 10 amp switch mode power supplies off Ebay I will repot further on the extremely bad workmanship soon. However I was wondering what authority one could send a complaint to about the unsafe nature of these supplies. One supply had a resistance of 8 ohms between earth and the main metal body and 200 ohms between the metal lid and earth. On investigation I found the circuit board to be a nightmare, with hr solder joints everywhere. Some components not even properly soldered in, I could move the output choke and capacitors making the wires slide in and out of the circuit board.
I have repaired both power supplies and now have less than 0.1 ohms between earth and the metal case. They also appear to work as they should.
