Deciphering Wired Rings Specs

I am in Germany and am looking to purchase a Ring doorbell and trying to confirm if the existing doorbell transformer can support the Video Doorbell Wired model. The original Siedle Transformer puts out a stated 12V DC 2 Amps. The Ring DIN Transformer which you can buy in Europe puts out 24 V DC, 0,42 A. The Video Doorbell Wired is supposed to be compatible with anything providing 8–24 V AC, 10–40 VA, 50/60 Hz. What is throwing me is the fact that the Ring provided transformer states an output of 24V DC while the Video Doorbell Wired states it needs 8-24V AC yet its supposed to work with the Ring provided DIN Transformer which has 24V DC. What am I missing here?
