Re: How much heat sink?
Thanks for all the input,heres my problem,I'm on my 3d ssr,the1st one I mounted right inside my controller box(no heat sink)the 2nd one I mounted to a piece of 1/2"aluminum(both ssr's were 40 amp I'm drawing 34)the 3d one I went to a 60 amp ssr,got some heat sink from a old pc but before I mounted the ssr I took apart one of the bad ones and used the bottom base plate for what I thought would be more sink but it still blew after a couple of minutes.I set the controller for 150 degrees,it hit that temp then shut off,I then set it for 300 degress and on the way up it blew.Any ideas?
