Help needed for Transformer

Hello, I have just purchased the doorbell wired and am having trouble working out if my existing transformer will suffice.
Can anyone help me and advise if my current transformer will do. The website says that transformer should be 8-24 VAC the pic is of my transformer but I can’t work it out from looking at it, as it doesn’t say VAC. Any help appreciated, Amanda

@Franky1962 That should be fine. That transformer is basically 12VAC.

Thank you for your response
