Great for pwm control
Im using one of these 40 amp SSRs to PWM a transmission cooler fan up under my jeep. Been installed for about a year now and so far no issues. If you use it to control a motor you have to run a fly back diode to keep from ruining the SSR. Thats what the 3 black rectangles with red a black wires running to them are. Gonna buy another one of these to pwm a windshield washer pump for water injection pre turbo (cheap turbo, dont care about the compressor wheel)

Arrived broken.
Arrived non functioning. The output circuit is always on. Fried my induction board with this thing. Will try a different one and test again but as of now, 1 star and I have to buy a new board.

Works flawlessly with Arduino
Allows me to switch high current loads on and off using an Arduino. My grandson and I are playing with peltier devices for a controlled temperature box (not a fridge). It heats and cools, using six 7 amp peltiers, all switched on using the SSR. The coils of smaller individual relays draws much more current than the SSR and caused our display to dim.

YouTube is ur best friend wiring these up
I run a powder coating oven of of these works great

Worked until it over heated!
Used this in my solar setup for temperature control of charging my Lifepo4 batteries. It work for at least 3 weeks and then burned. I think it need a heatsink to prevent it from failing.

Perfect
I use this to control two power supplies and this thing works perfectly. It is controlling 13 amps which is not a big deal and it gets warm to the touch but nothing to worry about. I will put it on a heat sink for long term use.

Low noise and great product
This is an excellent relay, works perfectly and little noise (40db or so) when turning on

Nice for electronics projects
Great contactless and silent relay, this will last forever if its well configured and silicone paste applied for heath transfer

Does not actually Switch output power
Got 2 of these, One just shorted the output all the time so I always had 120VAC on the output (even with the control wires disconnected) the other 1/2 worked in that it only put out 60VAC when no input signal was given, then called up to 120V when a signal was sent
