Jan 1, 2017 at 10:40 | comment | added | user134640 | Thats what i was intending with fake. I have specifically read about multiple cases of a 12A triac being used and or not complete coverage by the internal resin they use. Other than that i know that the build quality is pretty okay. Just sadly as i cant really open the relay without destroying it then i though that trying to create an extra layer of "protection" (now i understand it really wasn't) seemed like a good idea. | |

If it's ultra cheap it may well be fake product. However, you design solutions for original product, why would you design solutions to handle a 'fake' when you don't know what about it is fake? Perhaps the fakes only use under rated Triacs: ul.com/newsroom/publicnotices/… or this: instructables.com/id/… ...what circuit mods would you do?? | |

Dec 31, 2016 at 23:37 | comment | added | Spehro 'speff' Pefhany | It should be noted that if the SSR you bought is 'unsafe' in any way, none of the suggested circuits (so far) will make the slightest improvement. For example, if the isolation fails it could certainly take out your ESP and quite possibly a computer etc. connected to it, and/or cause a serious shock hazard. | |

The circuit has been completely redrawn and hopefully it makes at least a little bit more sense than it previously did.
