Hello All,
I have a Kogan internet radio which worked fine for years and then conked out.
It seemed to me the power supply had failed, so I pulled it apart to have a look-see. It has a 100VAC-240VAC to DC voltage converter as one unit, and then follwed by a voltage regulator card which develops and sends various voltages off to different sections of the radio.
It turns out the initial 100VAC-240VAC to DC voltage converter has failed. 240AC in and nothing out!
I've proved this by sticking metal pins into the DC output wires and connecting an external variable DC power supply to these pins. The radio then plays again. Currently I'm feeding it 12Volts DC, and the radio stops working if I wind the voltage down to about 8 volts.
I'm not planning to try to repair the faulty module. My intent is to feed it with an external plug-pack. I have no circuit description or repair manual for this radio.
Mu question is this:
Does anyone know what the DC voltage output is from this particular
100VAC-250VAC module? Or what they typically are?I'd like to feed the correct voltage from a plug-pack into the subsequent multi-voltage regulator.
