Monobass Posted March 1, 2008 Report Share Posted March 1, 2008 Connection to the powersupply. Either the output of a 7V-10V transformer, or a wall adapter can be used. 500 mA is recommented, especially if a backlit display is used, but MIDIfilter and MIDImerger work also with ca. 100 mA. AC or DC doesn't matter, since the rectifier behind J1 converts to DC anyhow. Also the polarity has not to be taken into account.Ok.. so I have a 9V 3A bench supply. Is that ok? Does it matter that it's 3A compared to the recommended 500 mA?Also the polarity has not to be taken into account.This means connecting black or red either way round is fine right?Just being careful :) Quote Link to comment Share on other sites More sharing options...
nILS Posted March 1, 2008 Report Share Posted March 1, 2008 Ok.. so I have a 9V 3A bench supply. Is that ok?

It's a maximum rating. As you know from ucapps, you'll most likely not use more than 500mA = 0.5A. So, your PSU has about 2.5 Amperes left, which is good ;-) This means connecting black or red either way round is fine right?Yes. Just be sure to connect it to the right pins on you core ;-) Quote Link to comment Share on other sites More sharing options...
Monobass Posted March 1, 2008 Author Report Share Posted March 1, 2008 many thanks nILS :)J1 all the way! Quote Link to comment Share on other sites More sharing options...
