TWTADE 2PCS SSR-40 DA 40A DC 3-32V to AC 24-480V SSR Single Phase Solid State Relay ssr-40da

A good upgrade if you replace your heater bed

Using this product in a circuit for ten plus years, and performing flawless. A new project will get the same quality, highly recommend.

These are standard units (I have used many) and they work just like all their peers. However, these are the first SSRs I've ever bought that didn't come with a clear plastic cover. Not a big deal, just something I took as a given when I bought them.

as advertised

Used as slave controllers for Lowell sequencer system. As always worked great!

great product. used this with a arduino to control some lights

These relays should have been adequate, but one failed after only a short period of use. The failure mode was "on" and power reset was needed to turn them off. I replaced them with another brand of a higher rating - even though these should have carried the working load with generous margin.

They work great. I added heat sinks, just in case.

Just what I needed. I needed an ac to ac relay and these worked perfectly. Used them for a floor heat system where the thermostats were 24 bolt ac and the pumps were 120.

Noting bad to say so far. They power my smartified furnace fan and work reliably everyday since.

Worked the way I suspected they would

non testé normalement utilisé seulement a max 30 amperes

Wired this up to run my router vac whenever I turned on the cnc router spindle. No issues at all. I would recommend it.
