Would appreciate a heads-up on replacing a blown door bell/chime transformer.
The transformer, a very old Friedland "Surepunch" model sited in the loft space, went open circuit (though not before blowing a fuse in my old distribution box) and smells burnt. Because of the worrying burning smell, I removed transformer from it's 5 amp lighting circuit and replaced with a suitably rated mains junction box. Also booked in local electrician to sort out door bell transformer issue and replace old distribution box with new one, but that's a couple of weeks away.
Meanwhile, I'd like to educate myself a bit more about door bell/chime transformers so I better understand my options. I appreciate the entire old bell/chime setup could be replaced with a modern equivalent but I kind of like the idea of keeping the old setup going - albeit with a new power supply. I've contacted Honeywell Friedland and asked them to suggest a suitable replacement transformer. Heard nothing from them as yet so I started to Google and saw both stand-alone and DIN rail mounted transformers. Seeing as I'm having the old distribution box replaced, is a DIN rail mounted transformer designed to fit into a modern distribution box? Or should I opt for an equivalent transformer swap, assuming a suitable model is available (the bell/chime was wired to the Friedland transformer's 15V output - also had a 12V option - whereas 8V and 12V supplies seem much more common these days)? Maybe the old bell/chimes would work with a 12V feed?
Thanks in anticipation.
