Hi guys does anyone have a schematic for this PSU?
DPS-250AP-62
I have the DPS-250AP schematics from elektrotanya but they are not the same
As far as I can see this PSU (which comes from a Fujitsu TX100 S3 and are not cheap to buy!) has a problem with the standby PSU not running
When powered on via a light bulb it takes a surge of power then drops to nothing.
I have about 285V across B+ and B- going to a TNY777 which I am certain is supposed to be the 3.3V SB PSU - but it isn't running and so the main capacitors take a very long time to discharge to a safe level!
I suspect the main PSU section is probably OK
But before I take it apart to get the PCB out, which gonna be a bit fiddly to do, I was wondering if someone could kindly give me the schematic.
Best regards
Rich
