Hi,
I've bought off ebay a cheap psu with +5 +12 -5V supposedly available at the terminal.
-5V rail is actually blanked off and there is no extra tapping point on the coil/winding.
Could someone indicate how to build a circuit that can draw -5V out of available positive voltage?
Not sure how much current does KI or MK pcb require but it should 1/2 amp to 1amp at most I guess.
Thanks
