I tried to order the PSM11R-120 for BlackMagic design converters. Digikey suggested PSAC12R, but the plug did not fit the converters. (slightly too small) Any suggestion for a converter that actually works?
It is likely that black magic designs had a special version made of this power supply that has a different plug end other than the standard 2.1mmx5.5mm plug. you may need to go back to the OEM for a replacement power supply.

Sorry, what do you mean by going bak to the OEM?
Hello,
OEM would be the original equipment manufacturer which in this case I would say is BlackMagic Design. They may be able to provide a replacement power supply.

Hi DAHA,
What is the specific part number of the Blackmagic Design product for which you need this supply? Perhaps the documentation specifies the specific part number required or, unlikely but even better, the size of the specific plug which fits into the power jack on that product.
As a note, the power plug on the “standard” PSM11R-120 that we used to stock and on the PSAC12R-120-R are both 5.5mm outside diameter and 2.1mm inside diameter.
If it looks like the outside diameter on the plug for the PSAC12R-120-R is right but that the inside hole is slightly small, then you probably need a 5.5mm outside diameter by 2.5mm inside diameter plug.
If that is so, here’s a link to a number of 12V 10W+ power supplies which have the 2.5mm inner diameter power plug which would probably work for you.
