Hello all, my house's doorbell circuit uses a 10:1 step-down transformer... I'm getting 11.6 Vac on the secondary. Problem is if I want to install and power a Ring doorbell unit (Pro), it requires 16-24 Vac. It's easy enough to order a 24V transformer... but if the Nutone chime is designed to be only seeing 12V... the doubling of voltage might not be such a good thing. How can I use the higher voltage transformer with the same chime solenoid? Series resistor? Another step-down transformer... 2:1 turn ratio? Or might the voltage not really matter? Also, what kind of amperage is the chime seeing... I modeled this in spice and with 24 Vac the model predicted it would be seeing 29 A! That can't be right, can it? I haven't measure the actual circuit with an ammeter yet.
Some specifics on the solenoid should this help... it has an inductance of 4.11 mH and a resistance of 51 ohms.
All help greatly appreciated!
