Single Phase Solid State Relay SSR-50DA-H 50A SSR 50DA H DC to AC Relay Solid State Resistance Regulator

Worked with the Inkbird PID controller and the screws on the heat sink line up. They were able to deliver the next morning which saved my butt. I like the plastic shield over the contacts unlike the inkbird SSR's.

I used this as part of building a 110vac air compressor for my truck that runs off an inverter. It has been on for about a year now 100% trouble free.

Both first and replacement units died after limited use. I really wanted this to work. I wanted my low voltage (12vdc) thermostat in my motorhome able to run a 1500 watt Cadet Wall Heater I installed. And it worked wonderfully until it didn't. The frist one quit after just a few cycles. Second one lasted a little longer but within 48 hours it too quit. The light still registered receiving 12vdc, but the contacts inside quit working.

Runs cool to the touch, but I'm only pushing around 15amp through it. Has worked through multiple cure cycles in my oven with no issue. Cheap enough to buy another for a spare. I'm happy with it.

For the price this gets the job done but they certainly can't withstand the current flow that they state. I ruined two 50 amp relays on a 48 amp load, both popped within 30 seconds. The second one even popped when I had it thermal pasted and screwed to a large CPU heat sink with the fan running. I have used this brand however for much smaller loads and they have functioned without fail for ~ 5 years

perfect condition.

Works brilliantly

This SSR has all the hallmarks of a fake Fotek SSR. While these fakes tend to be of decent quality overall, do not expect it to actually be capable of the amperage that they claim. All of the fakes that have been dissected have been found to have MUCH lower rated TRIACs in them - the most common dissections I've seen were that of 25A SSRs, which were found to have 12A TRIACs, and another being 40A SSRs with 20A TRIACs. For what I'm using this for (500W 120VAC 3d printer bed heater that won't pull more then 5A), this will be fine, but if you try to run one of these fake SSRs up to their 'rated' capacity, at best it'll likely burn out pretty quick, at worst it could start a fire. Based on the dissections of fakes, I wouldn't recommend running them at more than 50% of the capacity that they claim.

Works great and as intended. Brand new, clean.... for those wondering. the current required to “activate” or “energize” the relay on the input is less the lower the voltage!! Which i thought was cool and counter intuitive but then again.... im not an electronics guru. At 5volts on the input, it only draws 6.70mA to drive the load!!

Mine arrived DOA. I'm hopeful that others have better luck, but mine when active, I had 110V in and 3.4V out -- and yes I've used SSR's before. I ordered from another company that specializes in electronics and it worked immediately out of the box.

Installé sur un mini réfrigérateur fonctionne à merveille

Didn’t work so returned it

very satisfied
