[QUOTE="SPECIAL LOCATION, post: 522331, member: 250"] Are you sure...? The Ring doorbells I have fitted state a supply between 8v to 24v is ok? AND.. Have you put a meter across the outputs to see what the actual voltage is? as you will probably find it is higher than the written values.. because the input voltage will probably be higher that the quoted 230v value.. And the output is proportional to the output... Personally I would use the 12v tap output.. rather than the 16v connection.. as the output voltages are generally higher than the written values.. The UK nominal voltage is 230v -6% or +10% which means you incoming supply could be anywhere between 216v & 253v.. which will alter the actual output voltages of your basic unregulated doorbell transformer.. None of your images actually show your existing transformer.. just the new transformer & the old doorbell.. The new transformer should simply replace the existing transformer.. with the existing bell by-passed.. [ATTACH type="full" alt="ring doorbell psu.JPG"]13144[/ATTACH] [/QUOTE]
