Let us wish you a happy birthday! Assuming construction is similar to what we found, it appears that as long as they are derated down to be within their 12A limit and have good heat sinking at higher power levels over maybe 6- 7A, they should probably perform OK.

Please try your search again later. Please make sure that you are posting in the form of a question. How is this physically wired? If we look at SSRDA internal circuit we can see that control circuit is isolated from load by using optics. We know that SSR voltage drop is about 1.

You’ll need an SSR rated for inductive load, zsr a random triggered type not zero-cross type. We’ll assume you’re ok with this, but you can opt-out if you wish. If you need to drive high current loads, it ser necessary to ensure overheat protection.

If you take any microcontroller or any other digital IC, you will see that their output current on single pin is very limited — varies around 20mA. MarkT Brattain Member Posts: T his is close to maximum junction temperature. It has a maximum load capacity of 12A. Contact details entered above are not used to send newsletters or other advertisements. The one parameter that seems to be critical with respect to average power output control circuits like the one I want to use is the minimum trigger pulse width.

They also appeared to be counterfeit and came from the same supplier, but I could not find any performance issue with them during testing and they were built with 80NF70 MOSFETs which should be up to the job to meet the full spec. I know about inrush surge current when a compressor starts but it should be well within the limits of the SSR. They are still very popular way of switching power electronics.

Elec guy 12 November, at 9: AmazonGlobal Ship Orders Internationally. RC snubber circuit reduces those spikes to ensure safe and reliable operation of SSR. A few weeks OK – then a terrible smell. I have also tried just putting it on the 5V pin just to lock it up, but can try it completely separated with a 5V walwart or the like.
