My Ring Pro v2 transformer has packed it in. I'm having difficulty figuring ouy which transformer to purchase. Mine is a Ring AUBT1-24 24V DIN Rail Transformer, grey in colour. The DIN Rail Transformer for Wired Video Doorbells (black) https://en-uk.ring.com/products/din-rail-transformer-gen-2 ) looks nothing like mine. Will this one work?
