Very effective switching capability.
Needed a relay to handle 130vdc switching for my electric car conversion triggered from 12vdc supply, this works brilliantly. So far working really well, am considering replacing other high load mechanical relays with similar SSR’s, will update later when used for a while to give overall feedback.

Very poor quality - some of them are DANGEROUS!
I took delivery of two. Both were being used at 110V DC, switching 20A. (well within ratings). The first one was just closed circuit (the power switching inputs shorted). The indicator didn't light and it destroyed the driver circuit. It turned out all four screw terminals were shorted to the heatsink. Re-build driver (with fuses) and tried the second one. At first it appeared to work - the indicator turned on and the switching circuit closed. Unfortunately when the driver tried to turn it off, it literally blew itself to bits! The metal plate on the back detached with half the transistor attached. Smoke coming out of the other bit. I've since replaced them with a pair of Futek SSR-40DD SSRs which work just fine.

Watch out for the leakage when in the off state in your usage designs
If you intend to use this device as a replacement for old style mechanical switch relays be aware that this device has a leakage when in the off state, so you can't rely on it as a total safety isolation device. Having said that, for motor control the application I am using it in it's fine, does the job and is easy to interface to driver electronics.

Direct replacement for cr10s pro 3d printer.
Perfect replacement for my solid state relay in the cr10s pro 3d printer. Direct replacement.

Works well on my 3D printer
Used on my 3D printer and stays at low temperature, unlike others I have used. It says 24 volt min but I use it at 12 volt.

Very poor, didn' last.
Usless didn't last above a couple of months. Running a resistive load of around 20 amp and now failed to closed circuit heater on continuously.

DC to DC works perfectly
Good quality item

this does ot work at 3.3V.
A 3.3v signal will not trigger this relay

relais discount
le relais de fonctionne pas correctement, input activé 12V --> output 220V ok , input oV----> 130V qui passe quand même! matériel à ne surtout pas acheter! très dangereux

Se calienta mucho
He intentado sustituirlo por el original de la impresora 3d creality cr10 s pro, pero tras varias pruebas se calienta muchísimo, tocando la parte posterior incluso llega a quemar. Lo he devuelto.
