Asmusr Posted June 26, 2014 Share Posted June 26, 2014 I finally got a real PEB, but I need a 230V -> 110V voltage converter to plug it into a Danish power socket. My question is how many watts the converter need to supply. I can see that the PEB has a 1.25A fuse which means a maximum load of around 140W, but how much does a PEB with standard cards in reality use?

eck Posted June 26, 2014 Share Posted June 26, 2014 (edited) My box warms with 56W and 7 cards plugged in. Though, only two TI cards are canon. Edited June 26, 2014 by eck Quote Link to comment Share on other sites More sharing options...
+Ksarul Posted June 26, 2014 Share Posted June 26, 2014 It may also be popssible to change the wiring in your power section of the PEB to set the transformer for 220V operation. Some of the square button ones can do this, some can't. I'll check to see if I have the specific wiring changes handy. It is a simple matter or moving some spade lugs to different positions on a connector. . . Quote Link to comment Share on other sites More sharing options...
Asmusr Posted June 27, 2014 Author Share Posted June 27, 2014 The fuse on the back has numbers 110, 120, 220, 240 and an arrow pointing to 110. Could it be that you simply need to turn the fuse to point to 240? 1 Quote Link to comment Share on other sites More sharing options...
+Ksarul Posted June 27, 2014 Share Posted June 27, 2014 That is correct, Rasmus. You just pull the block and turn it so the arrow is pointing to the correct voltage. It would also be a good idea to verify that the fuse is rated for the voltage you are using too--and the correct value for it as well. A PEB set for 240V would have about half the amperage of one set for 120V, and these are Slo-Blo fuses to account for startup surges.

Could it be that you simply need to turn the fuse to point to 240? I thought exactly the same thing when I got mine-surely it can't be that easy?

Stuart Posted July 1, 2014 Share Posted July 1, 2014 Just as an aside, I saw a link to this today - a full 3A switch mode regulator in the same TO3 package as the linear regulator used for (IIRC) the +5V PEB supply for the floppy drives. http://www.ezsbc.com/index.php/featured-products-list-home-page/psu5.html Quote Link to comment Share on other sites More sharing options...
