Ideal supply for Eufy doorbell.
The ideal power supply for a Eufy doorbell. Due to its high power output, it can be used with very long cable runs. It fits all standard DIN rails and is super easy to connect and select the correct voltage/power. Mines running constantly over two years-no issues excellent durability. However, this should still be installed by a qualified electrician, not as a DIY project.

Ideal for Eufy E340 but read my comments first,
Purchased for a Eufy E340 video doorbell but after reading some of the reviews was a bit concerned as to the higher than permissible voltage at the output, the specā did seem ideal so purchased anyway and conducted my own tests. Under no load the 24V tapping does indeed record 31V but this would drop according to the load at these terminals. To play it safe I utilised the centre tapping which read 15.6V under load and was an ideal trade off, all connected and running perfectly so if you are concerned about possible damage to your Eufy I would suggest connection to the first and third terminals from the left as in the images.

Finally no buzzing!!
We originally used a British General transformer from screwfix for our Eufy doorbell which was the one initially recommended. It gave off an awful humming noise which we could hear through the walls it was that loud. We later realised we needed a transformer with at least a 30VA output to power the Eufy doorbell (the one we had only gave out 8VA hence the annoying buzzing) this I was the only one we could find that was powerful enough and fit inside the DIN rail enclosure. It was easy to install and itās completely silent! Weāre so pleased with it!

Caution, check with multimeter before installing
Way out of spec, good thing I checked it before installing it, could have smoked my bell , okay using the centre tap, but be careful with this unit.

Prodotto di buona fattura e al prezzo più basso sul web. Ne avevo acquistato un altro qualche anno fa e tuttora lavora egregiamente per alimentare 4 elettrovalvole. Ho installato subito anche questo e sempre per alimentare elettrovalvole a 24V DC
