I have a customer with a 1HP 120VAC pump ùsing a smart device to time and control it.
Another person has tried some generic 25A 250V and 40A 380V SSRs with all failure. One 25A unit faled-open, one failed-closed(shorted), and the 40A unit failed-closed. All had heat sinks with proper compound.
I have assured this new customer that we can provide a reliable permanent solution, using an Opto22 product by an American company.
What will be the best O22 SSR product to use for this application? And what additional support components might be necessary to use with an inductive load such as this motor?
