I first encountered power "bricks" 10 or 15 years ago. They come in various sizes. Full brick, half-brick, and quarter-brick were common when I was watching, with the usual blizzard of output voltages. They are made by many vendors. There is lots of competition on two fronts: efficiency and watts/package. I think the original ones were targeted at phone company applications since they ran off 48 V. (That may have just been the ones I was paying attention to.) Other input voltages are also common. The input voltage typically has a 2:1 range. The pinouts are reasonably standard. I don't know if there is an official spec or everybody else copies the first company to get something good on the market. -- These are my opinions. I hate spam. _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
