Re: KRAFTWERK Power Supply BUILD THREAD

Re: KRAFTWERK Power Supply BUILD THREAD

Hi Joe,
I just a quick question about the fuse... I almost finished my PSU ( for 1X 511 and I just have built some gears for 24v) so can I use a fuse 2A or I must to put 3A for it?

Thanks for the great projects!

Jean
