What is the output current?
Is the output to be isolated? Input Ground connects to output Ground is not isolated.
How many do you need?
Is cost important? size?
Here is something small. (not knowing what you want) Link
It was designed for 110/220 vac but most will work on DC as well. Input voltage range: AC50V-277V DC70V-390V output 12V 300mA.

Hi Thanks for your response. The output rating is fine and thanks a lot. My only question is does it work on DC as well.
