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. If this minimum is not low enough, the trigger pulse must remain on too swr to be a reasonable control signal for turning the SSR on and off within a half cycle.
Since the manufacturer FOTEK is considered to be a good quality manufacturer overall, the common conjecture is that the failing parts are counterfeit and therefore presumably of inferior construction. Or you can use a 9V battery. Your email address will not be published. Fridge motors are induction motors, you need an SSR rated for such a highly inductive load with the right snubber circuitry.

September 13, at 3: I have no experience of SSRs but I do have a fridge controlled with an Arduino using an electro-mechanical relay. Inside a huge PCB factory: Product details Item Weight: I am not sure if the SSR is real or not, and some reports that there are fake ones that are underrated. Digital pin output voltage is limited to IS supply voltage like 3. DC-AC – Leakage current in state: Do not underestimate the size of the inrush current. But it shuts off after a few seconds.

Best way to do this is to attach heatsink to backplate. If you need to drive high current loads, it is necessary to ensure overheat protection. Well, is the SSR or any component overheating? Try just putting 5V on the SSR control. Enter your e-mail address, to which we will send a one-time notification when this product is available again.
