Re: How much heat sink?
Going back to what I said," Failure in the first few minutes " . I fired up my oven and had plenty of time for," Failure in the first few minutes " before any significant heat was felt on the SSR case let alone in the built in heat sink. Granted, i'm only running at 60% of rated capacity. I'm having a little problem with the 40 watt light bulb, which has a very thin glass enclosure that provides very little insulation to the filamint, so oviously the temp. increase is felt much sooner. With this in mind, it takes much longer for the heat to migrate out of the case of a SSR an into the heat sink, so once again, if failure ocurrs in the first few minutes it could very will be caused by a "overloaded SSR or a faluty SSR'. After all,a heat sink only provides surface area to disipate BTUs and temp DT drives this action , theres really no magic involved. Fred
