I bought this since it was reasonably priced and shipped overnight, and I needed it for a custom project with a tight timeline. It is overrated for my circuit, which only draws up to 2 amps, but I still mounted it to a quality heatsink. I may pull it for a different project some day so the extra capacity is nice to have. Used in a cooling circuit with a 12V control voltage that cycles the SSR multiple times an hour. Has been working just fine for weeks and I expect it will continue to do so.

Used this to turn network switch on/off to allow intranet supporting a security system to operate without outside hackers looking also. Using a 12volt DC power supply to turn net switch om/off as needed. Absolutely no problems experienced yet and don't expect any! Definitely recommend.

I purchased a couple of these to use as a replacement for the original relay controlling the compressor in a window AC unit which had developed an intermittent "contacts closed when coil deenergized" condition. At the cost of these solid state relays, it doesn't make sense to retain the "old tech" of an electro-mechanical relay when you can gain all of the benefits of a solid state device. Longevity is uncertain at this point, but I will be surprised if I ever have to replace it again, since I selected a new relay with double the load current rating due to the inductive load of the compressor.

I bench tested this SSR with an LED lamp load at 120VAC. I drove it from 3-15 VDC and observed the current draw from 8 to 11mA. In my application, I would prefer less current draw to having an LED indicator. But you can't beat the price and fast delivery via Amazon. This will be used to replace a thermal lamp timing switch in an ancient garage door opener, where I'm going for minimum parasitic drain on a control circuit. Expect a 10-11mA load if you use this relay in a 12VDC circuit.

Used these to control oven top and bottom elements. I deliberately oversized the SSRs to ensure safety margin. They work well. I did carefully apply heat sink compound and used a decent size piece of sheet metal as a heat sink.

I used it for a couple of months in a homemeade spot welder. Set the machine aside for a couple of months, went to dust if off, discovered it doesnt trigger. Traced the problem down to this guy. Now I'm two monthw past the return window.Weaksauce. I hate feeling taken advantage of as a consumer.

I bought this to replace a leaky, generic ssr which came with a pid kit. I wasn't satisfied with the ssr leaking voltage when off/open.This one has essentially no leakage.Idk exactly how to test amp draw, but the previous ssr was leaking 100 out of 120 volts (at low amperage, enough to power a neon indicator light, which was unwanted behavior).This ssr leaks 7 volts at presumably negligible amperage, meaning essentially not at all.(some minor leakage is apparently normal with solid state relays, but this one is much better in that regard than the one it's replacing).I haven't used it enough to know if there will be any problems with temp or durability, but I don't expect any issues. If this review is old and hasn't been updated, assume no problems ever occurred.I am using a heatsink with thermal paste, but in an enclosed box so no airflow, but also at less than half of the rated amperage (powering a smoker element that runs off of a 15 amp residential circuit. I can't imagine there's much inrush current, so 15 amps is probably max draw, and it's probably less than that).
