  • What SSR should I use?

    I am building my first powder coating oven and could use a little help. I apologize in advance if this is a stupid question.

    I am going to use the Auber SYL2632 PID controller and two 2000 watt heating elements

    I am not quite sure which SSR I should use. Would I need a 25A or 40A SSR?


    Thanks

    I would recommend the 40 amp SSR... or 2 25 amp... The load must not exceed 80% of the rated SSR, so the 25 amp unit would likely work... but at a lower margin of safety... I like overkill on components like these so they are rated to a much higher load. That way (Theoretically) they aren't "working" as hard as the smaller SSR. I also like ONE SSR per element for troubleshooting purposes.

        Be careful with cheap rubbish from China!!! I first noticed my elements weren't cutting out so decided to investigate and found my SSR in this state!! Also, after a bit of 'youtubing' found some others had the same problem with Fotek SSR's - even with increasing to 80amp versions!!

          The one you show here is a Counterfeit unit according to this Article.

            Interesting reading indeed... Just goes to show how its getting harder and harder to identify what is (or isn't) counterfeit!!!

              I've known about this seemingly forever... I have some good Solid Fotek SSR's that have been running for a VERY ling time without issues... Often see people saying how they're **** and just let them know it's likely not the real thing... Usually easy to identify as well.

              Just sharing the info...
