4pcs Solid State Relay SSR-25DA DC to AC Input 3-32VDC to Output 24-380VAC 25A 250V Solid State Relay Module

I have read some bad stories about some SSRs beeing fake/unable to consistently perform - even well below their rated amperage. So far, no issues with this one drawing about 10A at 120VAC. Mounted to a standard SSR heat sink, it barely gets warm during 30 to 45 minute intervals of run time.

Can activate the relay with 5 to 48 volts. I use it to turn on a CNC spindle. It’s a bit larger than I expected but not an issue

I recently purchase a new high-end receiver for my new theater room. My older receiver had a 110v switched outlet that I used to turn on a 110v relay which turned on my power amps. My new receiver doesn’t have a 110v switched outlet, instead it has a 12v assignable trigger output. So I purchased this SSR to trigger on from my stereo and power on my amps. It has worked great for the month or so since I connected it. Silent compared to my old large relay, and doesn’t “stick” on like my relay did occasionally due to the arcing of the contacts.

Having the relay and heat sink come together helps in designing projects. The relay works well in distributing power in electronics.

I tax these things pretty heavily running two 3500W heating elements. They are on a cycle timer to limit duty cycle and mounted to heat sinks in a fan vented enclosure with a fresh air supply so that helps. So far they have been reliable, which cannot be said for the last pair I tried.

Worked perfect for my downed heatpress!

Search online, these seem to be the same ones that are cheaply made and potentially dangerous. Inconsistent switching behavior, some needed 12V+ DC, some didn't work at all. Leaving one star because I'm nice

simple wiring, works as of 20 minutes of usage. ill update my review if i end up having issues with it
