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.

as advertised

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.

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

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

These relays were used to control a 120V 20A resistive load. They are rated at 40A. The load was limited to about 30% duty cycle by a cycle timer and good heat sinking and fan cooling was provided. On the initial use they suffered a simultaneous catastrophic failure. The relays exploded in their enclosure. Before and after pictures attached.

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

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.
