Hai all,
I got 1 240 AC to to output 12 volt 1 Amp switching power supply / converter module.
When I plug 10 A connector (Digital meter) to positive output DC of module and negative/ground (Digital Module) to negative output DC of module, then my converter module was suddenly burned (without load).
I'd no problem to test it out the current liked that from DC(battery) as direct source of voltage. Why?
Of cause I know the current can be tested by input positive(DC) to 10 A of amp meter and negative (Amp meter) to positive of component be connected, and ground componnet back to converter for safety in purpose.
