Awesome piece of tech I wish I knew about a long time ago.
I have been needing these for a long time and didn't even know it. Mechanical relays fail pretty quick in some applications and have other issues. This works perfectly with a control voltage of greater than 3 volts and is dead silent. No moving parts. The back is an awesome heat sink. Easy to mount and hook up. Love these things just ordered more.

Seems to work well.
Seems to work well for its purpose. I had to design a box with a cooling fan for my use case. It’s a relay for my 110v silicone heating pad for the bed of my 500x500mm 3D printer. It’s exactly what I needed and works well!

Two failed units
I had these set up as switching relays for DC solar diversion loads, load and control side volts and amps well within specified range. Each unit worked briefly, but both failed within an hour of use, and will allow current to flow through the load side with little resistance even when the control side is completely disconnected. Not recommended for any serious use.

Heat sink
Perfect fit. It does what it was designed to do.

I really like these but they need documentation!!
I've killed a couple accidentally because the output is one direction so if you feed in from the wrong direction for too long you kill it. Either toss in a slip of paper or label it better then these would be 5 star all day every day. And they get HOT so scrounge up some old computer heatsinks and JB Weld them on with a thin layer so you get heat transfer.

Good heatsink
This heatsink works great with my relay. Happy with purchase.

Perfect for switching on DC voltage
I have a DC-powered fan in my pinball cabinet that I wanted to turn on whenever certain effects happen, but the current draw of the fan was higher than the output from my electronics board allowed, so an SSR was needed. This takes an input current and when triggered turns on an output current for the fan. My only word of note - be sure and look at the diagram included with the SSR. I assumed I knew how it should be hooked up and was wrong - USE THE DIAGRAM!

Fails
Ran a circuit at 40 V 30 A before anyone asks. These things failed almost immediately. Went through four of these pieces of garbage.
