Door Bell Transformer. Power Supply Switch. Suitable For Wired Doorbells & Compatible With Ring/Chime/Smart Door Bell. DIN Rail Mountable. Mains Converter 8/12/24V. No Need For Batteries.

Works really well with my Trust video doorbell on the 12V terminals. It’s been reliable day-to-day and runs quietly with little to no noise. It’s also a bit of a rare find, as most transformers on Amazon seem to be DC, whereas many video doorbells (including mine) need AC—so it was great to find one that actually works properly. The only downside is that it doesn’t fit inside my old Deta chime housing, so I’ve had to leave it without the cover. That means the internals are visible, but it’s not really an issue for me.

Delighted with this. Easy to fit and immediately sorted the power to my wired ring bell which I couldn’t get to work on the older transformer. Solid piece and easily wired

Using a previous Friedland power supply My Eufy doorbell battery (but wired) doorbell was frequently disconnecting and going off-line for hours/days at a time. Since installing this power supply transformer and setting it to 20v 1A a few weeks ago IT HAS NOT DISCONNECTED AT ALL. I am SO pleased with it. A little tricky to install yourself (take care to switch off the main supply to the fusebox) but otherwise perfect.

Does the Job but you will need to buy a separate! plastic box to mount the transformer

I moved into a new build that had a Deta mechanical chime, and with this, I was able to reuse the existing wiring and upgrade to a Eufy doorbell without any issues.

Doesn’t work - got incredibly hot and literally went bang! Avoid!

works with the ring door bell

The doorbell wouldn't charge at all with this and it tripped the breaker. I bought a genuine Ring Din transformer and it worked first time. I might have had a faulty one, so it might work for others

Only delivers 14.4V AC.. also overheated as soon as 240V applied Dangerous item !!
