I have not seen a great number of linear power supplies with auto-ranging inputs but there are ways to do it. Most have a mechanical switch (sometimes a reversibe fuse holder) which changes a pair of primary windings to be driven either in series or parallel. Another way to do it (albeit very inefficiently) is to design for an enormous amount of headroom on the DC side so you can input a wider range. I would be curious as to how they did it on this power supply if you wouldn't mind having a look... -- seanadams ------------------------------------------------------------------------ seanadams's Profile: http://forums.slimdevices.com/member.php?userid=3 View this thread: http://forums.slimdevices.com/showthread.php?t=20844 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
