Eufy 2K wired doorbell Transformer


Need some help to connect Eufy 2k wired doorbell. I reside in the UK so the existing Chime (Deta 3504) will not work to provide enough power to the bell. I have read that a transformer with 16-24v output is required.

I have seen the below from Screwfix that I am planning to buy:

Wil this do the job if I remove the transformer from existing Deta doorbell and replace with the one in the link above? Not sure if it would fit inside.

Any suggestion or advice is greatly appreciate.
